Medical scanner

The medical scanner was a medical device utilized by Starfleet medical personnel in the 2260s. Similar in size and function to the hand scanner of the medical tricorder, the medical scanner was a small, portable unit designed to function separately from the tricorder and diagnose by means of auditory emissions.

With this device, a trained physician could diagnose an illness by scanning the patient and interpreting the sounds it produced to diagnose, for example, arthritis. It was phased out as integration between the scanner and the medical tricorder became more advanced and commonplace.
