EMH Mark I[]

Deep Space 9 []

This EMH was integrated into Deep Space 9 by Doctor Louis Zimmerman and used as the template for his new Long-term Medical Holographic program in 2373. He was initially activated by Zimmerman for a level 3 diagnostic, which he understood and complied with. When he overheard Zimmerman request the data transfer to the new hologram, he became concerned about being replaced. Zimmerman explained that the EMH was being "supplemented by a new long-term program," who upon seeing the new hologram who was given the appearance of Julian Bashir, complained that "He doesn't even look old enough to be a doctor." The new long-term hologram then proceeded to offer his advice that Zimmerman should delete the original EMH program, adding "Now that I'm here, why do you need an archaic piece of software like him?" Incensed at being referred to as "archaic", Zimmerman told the original EMH that they would discuss the situation another time before deactivating him. (DS9: "Doctor Bashir, I Presume")

This EMH, described in the script as "the normal HOLO-DOC", was played by Robert Picardo.

USS Enterprise-E []

Although she swore she'd never use the program, Dr. Beverly Crusher activated the USS Enterprise-E's EMH program when she needed to buy time for her, her staff, and patients to escape from sickbay when the Borg threatened to overrun it.

Once activated and explained the situation, the EMH protested that stalling wasn't in his program, and that "I'm a doctor, not a doorstop." She suggested that he could "do a dance; tell a story."

When confronted, he managed to distract the invading Borg anyway, by offering them analgesic cream for the severe skin irritations that Starfleet Medical research indicated that Borg implants caused. His program then fritzed as he was scanned by the incoming drones. (Star Trek: First Contact)

This EMH, who was listed as "Holographic Doctor" in the credits, was played by Robert Picardo.

USS Equinox []

The Equinox EMH was activated on the USS Equinox sometime after it became stranded in the Delta Quadrant by the Caretaker. He was, like his Voyager counterpart, also unnamed.

When the Equinox crew decided they wanted to take advantage of nucleogenic lifeforms to enhance their warp drive, they deleted the EMH's ethical subroutines in order to have it study the creature and optimize the effects their remains had.

After Equinox encountered the USS Voyager, the formerly injured Noah Lessing commented on how The Doctor was an "outstanding EMH," joking to Seven of Nine that "ours can barely hold a laser scalpel." (VOY: "Equinox", "Equinox, Part II")

During the skirmish between the two ships, Equinox EMH secretly passed his ship Voyager's shield frequencies in order to give the Equinox an edge. Upon being returned to Voyager, The Doctor confronted the other EMH who began threatening to destroy the holoprojectors with explosives that he'd planted. The Doctor simply ordered Voyager's computer to delete the Equinox EMH before he cut the link to the other ship, ending the Equinox's advantage over Voyager from the EMH's sabotage. (VOY: "Equinox, Part II")

This EMH was played by Robert Picardo.

He was identified in the scripts as the "Equinox Doctor". He identified himself, when contacting Equinox from Voyager, simply as "Doctor", while The Doctor, himself, referred to his counterpart as the "Equinox EMH" as he called for the computer to delete the program.

EMH backup module []

This version of The Doctor was contained in the EMH backup module and stolen from USS Voyager during an attack by the Kyrians sometime during the 2370s, in the immediate prelude to the Great War between the Kyrians and the Vaskans.

The module was recovered centuries later by the Kyrians, and the Doctor was reactivated by Quarren. Almost immediately, he helped reshape Kyrian and Vaskan history by debunking the Kyrians' warped view of Voyager's role in the Great War. Once the record was corrected and the two species had reconciled, he served as the Kyrian/Vaskan Surgical Chancellor for many years before finally taking a small vessel and setting course for the Alpha Quadrant in an attempt to trace the path of Voyager. He claimed to have "a longing for home." (VOY: "Living Witness")

Reassigned EMHs []

Following the determination that the Mark I's were defective, according to their creator in 2375, Lewis Zimmerman, "I tried to have them decommissioned, but Starfleet in its infinite wisdom overruled me and reassigned them all to work waste transfer barges. That's where you'd be too, if you hadn't been lost in the Delta Quadrant. Do you know how humiliating it is to have 675 Mark Is out there, scrubbing plasma conduits, all with my face?" (VOY: "Life Line")

In 2378, The Doctor later considered his authorship of the holonovel Photons Be Free as a social commentary, written on behalf of the "hundreds of EMH Mark Is" in the Alpha Quadrant, who were "identical to me in every respect except, they've been condemned to a menial existence. Scrubbing conduits, mining dilithium." He further drew a comparison of their plight, through his work, to that found in The Vedek's Song, which told the story of the Occupation of Bajor.

Some of those "condemned" to mining dilithium were stationed at a Federation mining colony, these programs were able to obtain bootlegged copies of Photons Be Free. One of the EMH miners found the holonovel "provocative". (VOY: "Author, Author")

These EMHs were played by Robert Picardo.

The fact that the reconfigured Mark I's could view holonovels suggests that they retained at least some level of sentience left over from their original medical programming.

EMH Mark II[]

USS Prometheus []

To address the flaws in the EMH Mark I, Dr. Zimmerman began work on the Mark II, a prototype of which was finished in time to be included in the sickbay of the USS Prometheus in 2374, six weeks before the ship was stolen by the Romulans. (VOY: "Message in a Bottle")

While the Mark I's outward appearance was a copy of its inventor, a disillusioned Dr. Zimmerman changed the outward appearance of the Mark II. Furthermore, the patterns of behavior of the following versions were designed to be more pleasant and courteous. To achieve this, Zimmerman initially tried to improve on the programming of the Mark I, but eventually decided to create the Mark II from scratch. (VOY: "Life Line") In addition to that, new ship designs like the Prometheus-class enabled full mobility for the EMH, as the whole ship was outfitted with holographic projectors. (VOY: "Message in a Bottle")

By 2377, the Mark II had been replaced by a Mark III, followed by a Mark IV. (VOY: "Life Line")

The Mark II was played by Andy Dick.

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

TV Guide's summary for "Message in a Bottle" lists the Mark II as "Dr. Bradley".
