A hologram is a three-dimensional construction that consists of photons, forcefields, and matter that is generated by holo-emitters or similar devices. Simple holograms can be of inanimate objects; more advanced holoprograms can create animated simulacrums of living beings that can interact with real people, and behave as sentient beings.

Medical applicationsEdit

The most widespread use of holographic technology in 24th century medicine was the Emergency Medical Hologram, or EMH.

Holographic technology has also been used as a stopgap measure to replace patients' damaged or missing internal organs. This method was first used by the EMH Mark I aboard the USS Voyager in 2371, when passenger Neelix had his lungs removed by Vidiians. (VOY episode: "Phage") Dr. Elizabeth Lense used this same method in 2377, after Crewman Bart Faulwell had his kidney, pancreas and spleen damaged by a projectile. (CoE eBook: Signs from Heaven)
