Emergency Medical Holographic Program

The Emergency Medical Holographic program (EMH) is a sophisticated hologram developed in the early 2370s by Starfleet and used on most Federation starships in the late 24th century. It was designed to provide short-term advanced assistance during emergencies in sickbay to the extent of literally replacing a starship's medical officer. (DS9: "Doctor Bashir, I Presume") The first starship to be equipped with an EMH was the USS Voyager, although the Equinox, which was commissioned sometime the previous year, also had an EMH program. (VOY: "Relativity", "Equinox") The formal name of the program is EMH Program AK-1 Diagnostic and Surgical Subroutine Omega-323.

There is an apparent contradiction as to which starship was the first to have an EMH. Although it is specifically stated in "Relativity" that Voyager was the first starship to be equipped with an EMH, it was later revealed that the Equinox, which had been launched months prior to Voyager, also had an EMH program. There is no canon explanation for this discrepancy, although it may be that Voyager received their EMH during construction while the one aboard Equinox was installed just prior to that ship's launch.

History [ edit ]

First activated on stardate 48315, it was developed by Dr. Lewis Zimmerman at the Jupiter Station Holoprogramming Center as the embodiment of modern medicine. The EMH was programmed with 5 million possible treatments from the collective information of 2000 medical references and the experience of 47 individual medical officers. The EMH was also supplemented with contingency programs and adaptive programs to learn while serving as a supplement of a normal medical staff in cases of emergency. It contains 50 million gigaquads of computer memory, which is "considerably more than most highly developed humanoid brains." (VOY: "Lifesigns")

Some biological Starfleet doctors objected to the use of the EMH. Doctor Beverly Crusher swore that she would never use one, although she was forced to do so in order to create a distraction while the Borg tried to assimilate the USS Enterprise-E, allowing her, her medical staff, and her patients, notably Lily Sloane, to escape from sickbay. (Star Trek: First Contact)

The Doctor, a Mark I, originally objected to being the replacement for the entire medical staff of USS Voyager, as the EMH program was only meant to function for a maximum of 1,500 hours (62.5 days); after this time, memory degradation would occur. Fortunately, with the help of his colleagues, his program was altered to overcome this shortcoming. (VOY: "The Swarm") Starfleet would later request a holoprogram designed to operate as a full-time doctor in any posting where life support or living space was at a premium and the primary mission did not require the doctor to leave sickbay. As a result, the research and design for the Long-term Medical Holographic program was begun in mid-2373. (DS9: "Doctor Bashir, I Presume")

As of 2376, there have been four versions of the EMH, called Mark I, II, III and IV. The Mark I's outward appearance was a copy of its inventor, Dr. Zimmerman. However, as the Mark II was released to overcome the defects of the Mark I, the first version soon became obsolete and, thus, was reconfigured for menial tasks such as to scrape plasma conduits or to mine dilithium ore. At least 678 Mark I's were created – 675 reconfigured for menial tasks, one aboard Voyager, one aboard the Equinox, and the backup copy of Voyager's EMH which is in possession of the Kyrians – assuming these were not counted among those reconfigured. (VOY: "Life Line")

Furthermore, the patterns of behavior of the following versions were designed to be more pleasant and courteous and their outward appearance was changed. In addition to that, new ship designs like the USS Prometheus enabled full mobility for the EMH, as the whole ship was outfitted with holographic projectors.

After the EMH Mark II supplanted the "inferior" Mark I, the only remaining versions to fulfill their original programming were aboard the USS Voyager and the USS Equinox, which were both stranded in the Delta Quadrant and had to implement the emergency holograms for extended periods of time. In 2376, the Equinox EMH was deleted while in Voyager's database, leaving Voyager's program, "The Doctor", as the only Mark I still operating as an EMH.

Voyager's EMH (the Doctor) developed a distinct personality over the ship's seven-year-long journey to the Alpha Quadrant. Despite this, "the Doctor" was not granted the rights of a living person by a Federation Arbiter, although he did determine that "the Doctor" fulfilled the requirements of an artist under the law. The Arbiter did, however, encourage "the Doctor" to pursue recognition as a sentient being at a later point in time. (VOY: "Author, Author")

An ability unique to "the Doctor", Voyager's EMH was able to leave sickbay or the holodeck and to roam freely with the help of a mobile emitter (originating from 29th century technology)(VOY: "Future's End, Part II")mem. The Voyager's EMH was even given the responsibility of commanding the ship as the Emergency Command Hologram (ECH) if the ship's commanding officers were not present, incapacitated, or even dead. (VOY: "Tinker Tenor Doctor Spy", "Workforce", "Workforce, Part II", "Renaissance Man")

When the Doctor was sent in a holographic data stream to contact the USS Prometheus, he found the starship in the hands of Romulans, who had killed the Starfleet crew and captured the ship. The Doctor activated the ship's EMH, a Mark II, to help him recapture the ship, although the Mark II initially preferred to just deactivate and wait for rescue, and then treated the Doctor as inferior despite the other's vastly superior experience of life in general. The Doctor ultimately persuaded the Mark II to take action and help him. They planned to disable the Romulans by venting an anesthetic gas, but The Doctor was captured by the Romulans when he attempted to reach the environmental controls on the bridge. During the Doctor's interrogation, the Mark II simulated a bio-hazard, opening the vents which released the gas, knocking out the Romulans. The Doctor and the Mark II successfully fought off Romulan warbirds using the ship's experimental weapons systems, and returned the ship into Starfleet's hands, and informing them that Voyager was in the Delta Quadrant. (VOY: "Message in a Bottle")

Deep Space 9 did not have an EMH installed as it was incompatible with the station's Cardassian technology. An EMH was installed in 2373 as a way to transfer its data into the Long-term Medical Holographic program (LMH). (DS9: "Doctor Bashir, I Presume")

It is unknown if the EMH was kept aboard the space station.

By 2376, the Mark II had been replaced by a Mark III, followed by a Mark IV. (VOY: "Life Line")

Neither the Mark III or Mark IV programs were shown on-screen, nor was it revealed what happened to the Mark II.

Mechanics [ edit ]

• The EMH is a holographic simulation of a Human, but with no internal organs beneath the apparent surface to conserve computer power. EMHs are not equipped with reproductive organs. The Doctor, however, wrote additional routines into his holomatrix to facilitate romantic endeavors and has also had several relationships, one of which resulted in a son. (VOY: "Message in a Bottle", "Blink of an Eye")
• Holodecks use omnidirectional holographic diodes. A sickbay is fitted with a system of OHDs that project an image of the EMH. Each projects a complete image. Visible portions change as the hologram moves, creating an illusion of fluid motion.
• Magnetic containment fields allow the EMH to interact with physical objects. These force fields move as the EMH moves to create the appearance of solid matter. The containment fields can be shut off, allowing objects and people to pass through them – an EMH's cohesion can range from solid to intangible. (VOY: "Phage")
• When OHDs and magnetic field generators are added to other parts of a ship, they allow the hologram to leave sickbay (as in more advanced Starfleet ships).
• The universal translator algorithm is written into the EMH's matrix. (VOY: "Gravity")

Emergency Medical Hologram

• View history

The Emergency Medical Hologram or EMH is a sophisticated holographic program used upon Starfleet starships and facilities in the late 24th century to assist medical staff in times of emergency. The program whose formal name is EMH Program AK-1 Diagnostic and Surgical Subroutine Omega-323 was developed by Doctor Lewis Zimmerman on Jupiter Station . ( VOY episodes : " Lifesigns ", " The Cloud ", " Projections ", " Inside Man ", " Life Line ", DS9 episode : " Doctor Bashir, I Presume ")

History and specifications [ ]

EMHs are programmed with five million possible treatments from the collective information of 2000 medical references and the experience of 47 individual medical officers, as well as having adaptive programming for situations outside of those in their database. EMHs are only meant to be used a temporary measure to assist existing medical staff, or in extreme cases, to temporarily replace them until a new doctor is assigned. ( VOY episodes : " Caretaker ", " Future's End, Part I ")

Work on the EMH program began as far back as the year 2360 which was conducted by Starfleet Medical , though information on it was known only to a few individuals. ( ST - The Lost Era novel : Catalyst of Sorrows )

Zimmerman's initial proposal for an Emergency Medical Hologram was presented in 2365 to Doctor Beverly Crusher , Chief medical officer of the USS Enterprise -D . ( VOY short story : " Bedside Matters ")

By the time the holographic matrix was completed in 2370 , it had to have official approval by Leonard McCoy . ( TOS - Strange New Worlds II short story : " Doctors Three ")

The Mark I EMH was modelled on Doctor Zimmerman, in both its physical characteristics and personality. This was considered a flaw in the program's design by many Starfleet medical personnel, including Doctor Elizabeth Lense of the USS Lexington . ( SCE eBook : War Stories, Book 1 )

Lense later came to appreciate the Mark I EMH's lack of simulated emotionalism. ( SCE eBook : Out of the Cocoon )

Starfleet thought the Mark I's personality was too abrasive. ( DS9 short story : " So a Horse Walks into a Bar... ")

Given these reactions, the Mark I was quickly replaced on many ships by newer versions. ( VOY episode : " Life Line ")

The existing Mark I EMHs were reprogrammed for more menial tasks, such as scrubbing plasma conduits and mining dilithium ore. ( VOY episode : " Author, Author ")

Several Mark I EMHs continued to serve in their intended roles, including " The Doctor " of the USS Voyager and the EMH on the USS Equinox : both vessels being stranded in the Delta Quadrant , did not, of course, have access to upgraded versions. ( VOY novelization : Equinox )

A Mark I EMH also remained on the USS Enterprise -E into 2379 , as Chief medical officer Doctor Beverly Crusher preferred it to later versions. Although Doctor Crusher had previously mentioned that she had sworn to never use the EMH. ( TNG movie : First Contact , TNG - A Time to... novel : A Time to Sow )

The USS Destiny also had a Mark I EMH. ( DS9 short story : " Second star to the right... ")

The Soong Foundation discovered that more than 600 EMH Mark I models were put into servitude by Starfleet mining dilithium . Soong Foundation attorney Alyssa Cogley-Shaw sued for an injunction for Starfleet to reveal the status of all of its holographic programs. She claimed this was the slavery of sentient lifeforms, but Starfleet appealed the injunction claiming that the Mark I models are photonic tools. ( STO novel : The Needs of the Many )

Later versions [ ]

EMH Mark II in 2374 .

The EMH Mark II was programmed with new physical characteristics and to be a much more polite and friendly individual, although some felt it was too skittish. New starship classes such as the Prometheus -class were fitted with shipwide holographic projection systems so that EMHs could attend emergencies outside of sickbay. ( VOY episode : " Message in a Bottle ", DS9 short story : " So a Horse Walks into a Bar... ")

The EMH Mark III came into general use during the height of the Dominion War , and included stringent security protocols. It also featured an improvement of its personality subroutine over the previous models. However, following the end of the war, these security measures came to be viewed as a hindrance to effective caregiving. ( TNG novel : Losing the Peace )

The EMH Mark IV came into use in early 2376 , replacing the Mark III. ( VOY episode : " Life Line "; TNG novel : Losing the Peace )

EMH Mark VI in 2409 .

The EMH Mark VI usage was unknown though it was still in operation on starships by 2409 as seen on the USS Khitomer . This version had pale, blueish skin and a personality similar to that of the Mark I. ( ST video game : Star Trek Online )

The EMH Mark IX was online by 2380 . This version looked like a young, female with strawberry-blonde hair, and could replicate herself as necessary. A Mark IX nicknamed "Nina" was active aboard the Enterprise in mid 2380. ( TNG novel : Greater Than the Sum )

Nina was often used following heavy combat, especially during the Borg Invasion of 2381 . ( ST - Destiny novel : Mere Mortals )

Following a refit in early 2386 , the USS Titan was equipped with a Mark IX. ( TTN novel : Sight Unseen )

The EMH Mark XI was in use by 2381 . ( VOY novel : Full Circle )

History [ | ]

In 2371 the Chief Medical Officer of the U.S.S. Voyager was killed when the ship was hurtled 70,000 light years into the Delta Quadrant by the Caretaker , prompting The Doctor to be activated in his place. Over the following years, he would grow and develop beyond his original programming, becoming an invaluable member of Voyager' s crew.

In 2373, during a temporal incident involving time travel back to 20th-century Earth , The Doctor acquires a mobile emitter , allowing him to leave the confines of Voyager' s sickbay and holodeck and even participate in away missions. In 2378, he returns to Earth with Voyager .

In 2382 , the Doctor sues Starfleet which wants to confiscate the mobile emitter in order to study the device. Based on the " Data -precedent", the Doctor wins the lawsuit as he is considered a sentient being and the loss of the emitter would greatly decrease his quality of life. The following year , the case is re-opened, as the Data-precedent merely clarifies the Doctor not to be Starfleet's property, without implications for him being sentient or not. Around the same time, the Soong Foundation , which is dedicated to promote the rights of artificial lifeforms, announces its plans of creating their own line of mobile emitters.

In 2389 , the Soong Foundation is defending the Doctor. In the hopes of eventually freeing the 600 other EMH Mark Is working in dilithium mines, his lawsuit is expanded to encompass all sentient artificial lifeforms in the Federation. Five years later , the lawsuit is finally concluded, with the Judge Advocate ruling that the Doctor is indeed a sentient being and has the right to choose how he wants to live. None of the other EMHs are freed yet, though.

With the mobile emitter being his approved property, the Doctor accepted a commission as a Lieutenant Commander in Starfleet and took the post of Chief Medical Officer at the research facility on Galor IV in 2395 . Here, he also cooperated with the Starfleet Corps of Engineers, who were allowed to study the mobile emitter.

By 2410 , the Doctor is assisting in the efforts of the Delta Alliance to explore the newly-accessible Delta Quadrant.

Celebrating The Ships of The Line: The USS Prometheus

The USS Prometheus NX-59650 was the second ship to bear the name Prometheus and, when she was launched from the Beta Antares Ship Yards in 2373, was Starfleet's fastest vessel -- with a warp factor of 9.99. An experimental prototype -- and dedicated warship -- created for deep space tactical assignments, the Prometheus was equipped with regenerative shields, multi-vector assault mode and ablative hull armor. The ship was also equipped with holographic projectors on every deck, allowing its EMH Mark II unimpeded movement throughout the ship.

Romulans hijacked the Prometheus in 2374. It was during this time that the USS Voyager, then stuck in the Delta Quadrant, sent a subspace transmission that was received by the Prometheus. In it was hidden Voyager's EMH, who pretended to be the EMH of the Prometheus and insisted he was a neutral figure in the Starfleet-Romulan conflict occurring aboard the Prometheus. The Voyager's EMH, a Mark I better known as The Doctor, activated the Prometheus' EMH, a newer Mark II. After putting aside their petty differences, the two EMH's proceeded to reclaim control of the ship by utilizing a neurozine gas to knock out the 27 Romulan hijackers. Once back on Voyager, The Doctor informed Captain Janeway that he told Starfleet of Voyager's situation and, as a result, Starfleet -- which long believed Voyager to be lost for good -- redoubled its efforts to locate Voyager. StarTrek.com 's look at the USS Prometheus NX-59650 continues our ongoing celebration of the Ships of the Line, which will carry on from now until the end of the year.

Emergency Medical Hologram

The Emergency Medical Holographic program (EMH) is a sophisticated hologram developed in the early 2370s by Star Fleet . It has been used on most Federation starships since the late 24th century. It was designed to provide short-term advanced medical assistance during emergencies in sickbay to the extent of literally replacing a starship's medical officer. The first starship to be equipped with an EMH was the USS Voyager . The Equinox , which was commissioned sometime the previous year, also had an EMH program. The formal name of the program is EMH Program AK-1 Diagnostic and Surgical Subroutine Omega-323 .

The EMH was programmed with 5 million possible treatments from the collective information of 2000 medical references and the experience of 47 individual medical officers. The EMH was also supplemented with contingency programs and adaptive programs to learn while serving as a supplement of a normal medical staff in cases of emergency.

Some biological Star Fleet doctors objected to the use of the EMH. Doctor Beverly Crusher swore that she would never use one, although she was forced to do so in order to create a distraction while the Borg tried to assimilate the USS Enterprise NCC-1701-E) allowing her, her medical staff, and her patients, notably Lily Sloane, to escape from sickbay.

As of 2376, there have been four versions of the EMH, called Mark I, II, III and IV. The Mark I's outward appearance was a copy of its inventor, Dr. Zimmerman. However, as the Mark II was released to overcome the defects of the Mark I, the first version soon became obsolete and, thus, was reconfigured for menial tasks such as to scrape plasma conduits or to mine dilithium ore. At least 678 Mark I's were created; 675 reconfigured for menial tasks, one aboard Voyager , one aboard the Equinox , and the backup copy of Voyager' s EMH which is in possession of the Kyrians ; assuming these were not counted among those reconfigured.

Furthermore, the patterns of behavior of the following versions were designed to be more pleasant and courteous and their outward appearance was changed. In addition to that, new ship designs like the USS Prometheus enabled full mobility for the EMH, as the whole ship was outfitted with holographic projectors.

After the EMH Mark II supplanted the "inferior" Mark I, the only remaining versions to fulfill their original programming were aboard the USS Voyager and the USS Equinox , which were both stranded in the Delta Quadrant and had to implement the emergency holograms for extended periods of time. In 2376, the Equinox EMH was deleted while in Voyager' s database, leaving Voyagers program, "The Doctor", as the only Mark I still operating as an EMH.

By 2376, the Mark II had been replaced by a Mark III, followed by a Mark IV.

• The EMH is a holographic simulation of a Human , but with no internal organs beneath the apparent surface to conserve computer power. EMHs are not equipped with reproductive organs. The Doctor, however, wrote additional routines into his holomatrix to facilitate romantic endeavors and has also had several relationships, one of which resulted in a son. It is unknown how a hologram could produce offspring, and The Doctor did not explain it.
• Holodecks use omnidirectional holographic diodes. A sickbay is fitted with a system of OHDs that project an image of the EMH. Each projects a complete image. Visible portions change as the hologram moves, creating an illusion of fluid motion.
• Magnetic containment fields allow the EMH to interact with physical objects. These force fields move as the EMH moves to create the appearance of solid matter. The containment fields can be shut off, allowing objects and people to pass through them. An EMH's cohesion can range from solid to intangible.
• When OHDs and magnetic field generators are added to other parts of a ship, they allow the hologram to leave sickbay (as in more advanced Star Fleet ships).
• The universal translator algorithm is written into the EMH's matrix.
• Most vessels above escort class come equiped with OHD. The list of ship classes that are equipped with OHDs in Sickbay are the Berlin, Sun-Tzu, Zeus, Einstein, Yeager, Avenger, Beckett, Vesta, Pulsar, and Federation classes. Medical ships of Star Fleet are occasionally equipped with OHDs, but this is not standard gear. The above classes are those that are considered to have the capability of projecting an EMH in Sickbay as standard-issue. Vessels of smaller size and limited accommodations, do not have the ability to project an EMH. Furthermore, ships with a warp core of producing a maximum of Warp 5.5 would usualy not have the power output to support OHD as it would be frivolous to the system. Escorts do not come up EMH, however, a major system such as replicators the torpedo launcher can be replaced to allow for an OHD an EMH program. Civilian ships rarely carry OHDs, as their cost is high enough that only the military vessel can install them on their starships.

The USS Apparition, an Apparition-class Infiltrator, is the smallest ship in Star Fleet to have the ability to project an EMH, due to its specialized holographic technology. However the maintenance on the OHD on this vessel is extremely costly, making the overall cost of the vessel equal to that of a Battle Cruiser.

The Doctor, a Mark I, originally objected to being the replacement for the entire medical staff of USS Voyager , as the EMH program was only meant to function for a maximum of 1,500 hours (62.5 days); after this time, memory degradation would occur. Fortunately, with the help of his colleagues, his program was altered to overcome this shortcoming. Star Fleet would later request a holoprogram designed to operate as a full-time doctor in any posting where life support or living space was at a premium and the primary mission did not require the doctor to leave sickbay. As a result, the research and design for the Long-Term Medical Holographic program was begun in mid-2373.

Voyagers EMH developed a distinct personality over the ship's seven year-long journey to the Alpha Quadrant , possibly due to the numerous alterations to his programming. It was granted all privileges and rights of a living person because of this. Furthermore, Voyager's EMH was able to leave sickbay or the holodeck and to roam freely with the help of a mobile emitter (originating from 29th century technology). The Voyager' s EMH was even given the responsibility of commanding the ship as the Emergency Command Hologram (ECH) if the ship's commanding officers were not present, incapacitated, or even dead.

When the Doctor was sent in a holographic data stream to contact the USS Prometheus , he found the starship in the hands of Romulans , who had killed the Star Fleet crew and captured the ship. The Doctor activated the ship's EMH, a Mark II, to help him recapture the ship. The Mark II initially preferred to just deactivate and wait for rescue, and then treated the Doctor as inferior despite the other's vastly superior experience of life in general. The Doctor's experience, after all, clearly showed not doing anything and waiting for rescue on a ship with vastly superior firepower to anything Star Fleet had at the time would be a stupid decision. This is ironic as the EMH Mark II was supposedly 'superior' to the Doctor.

The Doctor ultimately persuaded the Mark II to take action and help him. They planned to disable the Romulans by venting an anesthetic gas, but The Doctor was captured by the Romulans when he attempted to reach the environmental controls on the bridge. During the Doctor's interrogation, the Mark II simulated a bio-hazard, opening the vents which released the gas, knocking out the Romulans . The Doctor and the Mark II successfully fought off Romulan warbirds using the ship's experimental weapons systems, and returned the ship into Star Fleet 's hands, and informing them that Voyager was in the Delta Quadrant .

Emergency Command Hologram

• View history

The Emergency Command Hologram ( ECH ) was a holoprogram developed and implemented by the crew of USS Voyager while it was in the Delta Quadrant in the 2370s . It was an extension of the Voyager 's Emergency Medical Hologram to include strategic and tactical data in order to function in a command capacity in the event of the current command crew being incapacitated during an emergency. ( VOY : " Tinker Tenor Doctor Spy ", " Workforce ", " Workforce, Part II ")

Premise [ ]

The idea of an emergency replacement for Voyager 's commanding officer , Captain Kathryn Janeway , was first implemented in 2371 , after the ship encountered the Komar , a species of non-corporeal trianic-based energy beings . When it was determined that they could take over any organic being at will, Janeway concluded that " The Doctor is the only person on board we can trust at this moment, " and while facing the risk of the alien presence taking over the ship, she concluded that " I can't take the risk that it could take over any of the senior officers . " She therefore chose to transfer all of her command codes to The Doctor, " until further notice. "

Although The Doctor thought that they meant he was in command, Janeway clarified that he would " act as a failsafe . If you feel at any time that any one of us are under the influence of the alien, you can countermand our orders and take control of the ship. " When asked if he felt up to the task, The Doctor concurred, " Well, of course. I make life and death decisions every day. " After stating, " Computer, transfer all command codes to the holographic doctor. Authorization Janeway 841 alpha 65, " the seeds for the ECH concept were sown.

In spite of their good intentions, the Komar was one step ahead, and while possessing the body of Tuvok , while under the guise of reconfiguring the ship's sensor relays , disabled the EMH program, effectively locking out and encrypting his initialization routine . With The Doctor disabled, the command codes reverted back to Janeway, a point Tuvok later indicated, when stating, " if we assume the alien could not take over the holographic doctor, then logically it would try to force the command codes back into a humanoid host . " ( VOY : " Cathexis ")

Essentially, the ECH was designed to be a 'backup captain' which possessed information from all major Starfleet strategic and tactical databases . The ECH could incorporate the data into its plans for controlling the ship. It also had basic engineering skills in order to assess damage when necessary. The ECH could interact with the computer or use any console manually if desired as the captain would. While the computer can be ordered, when possible, to bypass or reroute systems to get the ship working again, the ECH could replace necessary components or otherwise manually repair any system required. ( VOY : " Workforce ")

The ECH was designed to have access to all areas of a ship, especially the bridge , which was only possible if the ship was outfitted with holoemitters or if the ECH was equipped with a mobile emitter , as The Doctor was. ( VOY : " Workforce ")

Once activated by a commanding officer, all command codes were automatically transferred to the ECH. At that point, the ECH became the acting captain of the ship. If available, the ECH was given directives from other crew or Starfleet to follow. If necessary, the ECH could function alone, ordering the computer to take any action necessary, such as maneuvering, sensor scanning, targeting and firing weapons, and opening communications. ( VOY : " Workforce ") The command codes also allowed for the ejection of the warp core through verbal command. ( VOY : " Renaissance Man ")

History [ ]

The ECH was first envisioned by The Doctor after he added a daydreaming subroutine to his program in 2376 . His initial request to Captain Janeway was denied, but, after The Doctor demonstrated his abilities in practice, Janeway reconsidered and ordered research into the development of the ECH. ( VOY : " Tinker Tenor Doctor Spy ") Design and testing would occur for the next several months. ( VOY : " Workforce ")

Janeway activated The Doctor's command subroutines in a real situation in 2377 when tetryon radiation forced everyone to abandon ship. Shortly after the ship was abandoned, Voyager was attacked by scavengers. He and the computer disabled one ship and evaded the others by hiding in a nebula. He managed to begin repairs, but when Commander Chakotay , Ensign Harry Kim , and Neelix returned from an away mission , life support was not yet online, because it was not an immediate concern to The Doctor. ( VOY : " Workforce ")

After Chakotay and Neelix sought the rest of the crew, who had been abducted by Quarren criminals , Kim and The Doctor disagreed about who was superior to the other; Kim was a commissioned officer, but The Doctor had information about all of Starfleet's great strategists. In one battle with the Quarren, The Doctor called up information about a Romulan battle from his tactical database, leading him to use a photonic shockwave against the ships, before retreating. In the final battle against the Quarren Harry Kim's plan to sabotage three escape pods and detonate them once in the enemies' tractor beams saved Voyager . This provided a lesson to The Doctor about experience. He realized that he was needed on Voyager as a medic more than as a commander, and made peace with Kim before handing back command to a rescued Captain Janeway. ( VOY : " Workforce, Part II ")

A trial on the rights of The Doctor was initiated when his holonovel was published without his permission in 2378 ; the publisher arguing that The Doctor had no legal rights due to his status as a hologram, prompting the crew to arrange a hearing to determine The Doctor's rights as a sentient being. Harry Kim cited the ECH extension in The Doctor's favor, regarding it as a Human desire to develop and change. While the publisher argued that this simply showed that The Doctor's program could be altered, Harry countered that The Doctor's request for the creation of the ECH represented a desire to improve that would not have been expected of a hologram designed to do a specific task. ( VOY : " Author, Author ")

Later that year, The Doctor disguised himself as Commander Chakotay and used his command codes to transform himself into the ECH. He would later eject the warp core, then escaped from the ship aboard the Delta Flyer with the warp core to exchange it with the Hierarchy for Captain Janeway's freedom. Both Janeway and the warp core were recovered and returned to Voyager , although The Doctor remained in sickbay for a week out of embarrassment about the "deathbed confessions" he had made while the excess subroutines installed by the Hierarchy were being deleted. ( VOY : " Renaissance Man ")

Emmie (EMH Mark IV)

• Edit source
• View history

The Emergency Medical Hologram Mark Four ( EMH Mark IV ), also known as Emmie, is a Holographic program deployed on the USS Prometheus with the intention of providing assistance to Starfleet medical personnel in an emergency or to take command of said medical personnel if the Chief medical officer or Assistant Chief medical officer are unavailable and no one among the present medical personnel is assuming the leadership role in the absence of the Chief medical officer or Assistant Chief medical officer. ( Star Trek: Prometheus )

History [ ]

In 2379 , the Emergency Medical Holographic Program AK-1 Diagnostic and Surgical Subroutine Omega 323 Mark IV, of the starship Prometheus personalized her appearance, expanded her personality subroutines, and named herself Emmie (a name based on the name of her program) with the blessing of Captain Logan MacLeod , in an attempt to differentiate herself from the other Mark IV EMHs and so she could relate better to the crew and guests on board the Prometheus .

In late 2379 , Emmie began developing friendships with various crew members, including Erin Denali , Atana Ral , Tahna Malyik , and Celes Tal all of which helped the crew to regard her as a person and not just a program. Emmie also came to regard Lou , the vessel's other holographic crew member, as a cousin - a feeling which he reciprocated.

Screen Rant

Star trek: voyager & ds9 crossed over in the mirror universe.

Despite being stuck in the Delta Quadrant, a Star Trek: Voyager crew member briefly crossed over into the Mirror Universe to join the DS9 cast.

• Star Trek: Voyager and Deep Space Nine crossed over within the Mirror Universe, bringing the shows together across vast cosmic distances.
• The crossovers featuring characters like Tuvok and Doctor Zimmerman added depth to the interconnected Star Trek universe.
• Despite differing tones, Voyager and DS9 remain beloved shows, delighting audiences through streaming platforms today.

Despite being separated by thousands of light years, Star Trek: Voyager and Star Trek: Deep Space Nine crossed over inside the Mirror Universe. Voyager and Deep Space Nine were very different in tone, due to the differing approaches of the shows' respective producers, Brannon Braga and Ira Steven Behr. Where DS9 was a serialized drama that tackled huge themes, Voyager embraced a traditional episodic approach that could sometimes feel disposable and regressive . Despite their differences in tone, DS9 and Voyager are two beloved Star Trek TV shows that still delight audiences to this day via streaming, which is a testament to the versatility and timelessness of the franchise.

As the USS Voyager was stranded in the Delta Quadrant, it was hard, but not impossible, for Star Trek: Voyager to cross over into Star Trek: Deep Space Nine 's Alpha and Gamma Quadrant settings. In fact, there was a surprising number of Star Trek characters who guested on Voyager from Captain Hikaru Sulu (George Takei) to Commander William T. Riker (Jonathan Frakes). Creative approaches such as intervention by Q (John de Lancie), glimpses of Starfleet's attempts to locate the missing USS Voyager, and even the Mirror Universe allowed Star Trek: Voyager to crossover with its 1990s contemporaries, including Star Trek: Deep Space Nine .

Every 1990s Era Star Trek Crossover

Star trek: voyager’s tuvok crossed over with ds9’s mirror universe, star trek: deep space nine, season 3, episode 19, "through the looking glass".

In Star Trek: Deep Space Nine season 3, episode 19, "Through the Looking Glass", Commander Benjamin Sisko (Avery Brooks) is captured and taken to the Mirror Universe by "Smiley" O'Brien (Colm Meaney). The Rebellion in the Mirror Universe wanted Prime Sisko to convince the ex-wife of his Terran counterpart to join the resistance against the Klingon-Cardassian Alliance . As Sisko is taken to the Terran Rebellion's enclave, he meets the Mirror Universe variants of his DS9 crew mates. In the same scene Sisko also meets the Mirror Universe version of Star Trek: Voyager 's Lt. Tuvok (Tim Russ), leading a more logic-driven faction of the Rebellion.

Mirror Tuvok is the only Mirror Universe variant of a Star Trek: Voyager character that has appeared on TV.

Tuvok was included in "Through the Looking Glass" at the request of Rick Berman , who presumably wanted to strengthen the links between Star Trek: Deep Space Nine and Star Trek: Voyager . DS9 season 3 and Voyager season 1 aired concurrently with each other, and "Through the Looking Glass" aired on April 17, 1995, a week when there was no new episode of Voyager . In this gap between "State of Flux" and "Heroes and Demons", therefore, a brief crossover between Voyager and DS9 was a good way to keep the fledgling Star Trek show in the minds of the audience.

Every Voyager & DS9 Star Trek Crossover

"Through the Looking Glass" isn't the only crossover between Star Trek: Voyager and Star Trek: Deep Space Nine . The Voyager pilot "Caretaker" features the USS Voyager depart from Deep Space Nine to search for the missing Tuvok and the Maquis ship, the Valjean in the Badlands. As with McCoy and Picard in the previous Star Trek pilots, DS9 's Quark (Armin Shimerman) appeared in "Caretaker" to pass the baton to Voyager . In a scene that demonstrated how green the young Ensign Harry Kim (Garrett Wang) was, he almost falls for one of Quark's latest scams, until he's rescued by Lt. Tom Paris (Robert Duncan McNeill).

Gul Evek (Richard Poe) and Morn (Mark Allen Shepherd) are the two other Star Trek: Deep Space Nine characters that appear in the Star Trek: Voyager pilot.

A version of Star Trek: Voyager 's Doctor (Robert Picardo) appeared in Star Trek: Deep Space Nine season 5, episode 16, "Doctor Bashir, I Presume" alongside his creator Dr. Lewis Zimmerman (also Picardo). Technically, Star Trek: Deep Space Nine marks the first real appearance by the EMH's creator, who had previously appeared in Voyager as a holographic replica. The real Zimmerman would later appear in Star Trek: Voyager season 6, episode 24, "Life Line", which also featured Lt. Reginald Barclay (Dwight Schultz) and Counselor Deanna Troi (Marina Sirtis) further strengthening the bonds between different corners of the Star Trek universe.

All episodes of Star Trek: Deep Space Nine and Star Trek: Voyager are available to stream on Paramount+.
