where did the doctor get his mobile emitter
The Doctor (Star Trek: Voyager) The Doctor later acquired a mobile holographic emitter from the 29th century.[4] Although he had previously been confined to Sickbay or the Holodeck, the mobile emitter allowed The Doctor to move about freely, making him ideal for missions where the environment would be harmful or otherwise fatal to the crew. In one notable incident, when an away team was trapped on a radioactive planet, The Doctor was able to infiltrate the people and almost single-handedly rescue the team because, as he pointed out, being a hologram renders him immune to the radiation, stating that "being a hologram does have its advantages."
Doctor Who in Canada and the United States In 1978, Tom Baker's first four seasons as the Doctor were sold to PBS stations across the United States. This time, though, Time-Life was ready to have the Doctor poised for American consumption, by having stage and screen actor Howard Da Silva read voiceover recaps of the previous episode and teasers for the next one which would inform the viewer as to what was going on. To accommodate the teasers up to three minutes of original material was cut from each episode. PBS program planners took the show at face value, but it soon achieved cult status. A few commercial stations including WOR in New York and KVOS in Bellingham[4] also aired the show for a few years.
