: This article refers generally to the fictional Star Trek technology, the Emergency Medical Hologram. For the character in Star Trek: Voyager, see Doctor (Star Trek). In the Star Trek fictional universe, the Emergency Medical Hologram or EMH (full name: EMH Program AK-1 Diagnostic and Surgical Subroutine Omega-323) is a holographic program intended to support and augment medical personnel aboard a Starfleet vessel or installation in case of emergency.
History The EMH was introduced and is most commonly seen on the series , as played by Robert Picardo. The producers based the idea on the hologram character Moriarty, who achieved self-awareness in The Next Generation, and considered introducing the concept of the EMH in a seventh-season episode of , but this was not followed up.The program also made appearances on and the movie . It should be noted the kind of holograms used in "Star Trek" in general and the EMH system in particular are "solid", and not mere three dimensional images (see: Holodeck for a more in-depth explanation of the technologies used to achieve this). The holographic personification of the EMH program can therefore manipulate objects and perform surgery just like a real doctor. The limitation however is that the EMH can only operate in an area covered by a compatible holo-emitter; this, the standard EMH is usually confined to Sickbay, though on larger, more modern ships, such as Prometheus-class, additional holo-emitters are often installed in other key areas of the ship, such as the Bridge and the Engineering section, as well.First activated on Stardate 48308, the EMH was created by Dr. Lewis Zimmerman, with assistance from Lt. Reginald Barclay. It possesses one of the Federation's most extensive medical databases, containing information from over 3,000 cultures and the personal experiences of 47 specific surgeons. The program itself is built on an adaptive heuristic matrix, pioneered by Dr. Zimmerman, which allows the EMH programs to learn and adapt quickly to new situations.Four versions of the EMH series have been created to date (only two were seen on screen, the Mark I from "Voyager" series and the Mark II from the "Message in a Bottle"), the Marks I, II, III, and IV. While the status of the latter three incarnations is unknown, the Mark I programs, based on Dr. Zimmerman himself and possessing his short temper and numerous other foibles, earned them deprecating nicknames including "Emergency Medical Hotheads" and "Extremely Marginal Housecalls". They clearly failed to meet Starfleet's expectations and were re-assigned to menial labor; "Photons be Free") seems to suggest compulsory servitude, even slavery.The only Mark II to appear on screen was in "Message in a Bottle", aboard the USS Prometheus. The Mark II (played by Andy Dick) believed himself to be far superior to the Doctor, but the two had to work together to help retake the ship from Romulan captors.Only three Mark I's avoided the aforementioned re-assignment to menial labor. Two of these were the EMHs of Voyager and Equinox, both of which were stranded in the Delta Quadrant by the Caretaker. Of these two, only Voyager's EMH (known as "The Doctor" to the crew) survived.
