Star Trek: Voyager - Lifesigns Season 2 Episode 19
Stardate: 49504.3 Voyager answers the distress signal of a Vidiian ship and transports the lone occupant to sickbay. The occupant is suffering from the Phage, and near death. The Doctor puts the unconscious patient into a coma, but then he links her brain’s synaptic activities to a holodeck created virtual rendition of the Vidiian without the disease. When she wakes, the Vidiian gazes upon a healthy face she had not seen since she was seven years old. However, the holo-image will only keep her alive for a short period of time. The Vidiian, a hemotologist, and the Doctor work together to restore her synaptic functions to her old body before her brain waves disappear and she dies.
