Tomographic imaging scanner
From Memory Alpha, the free Star Trek reference.
A tomographic imaging scanner was a device designed to function as a sensor. The scanner was capable of multiphasic resolution and could penetrate significant amounts of subspace interference.
The Daystrom Institute began work on such a device in the 2360s, but it remained theoretical in 2364, when, in an alternate timeline, its use was suggested by Lieutenant Commander Data, during the course of an analysis of an anti-time eruption by the USS Enterprise-D. The device had been developed and built by 2370 and installed aboard the Enterprise-D, when it was used by Data in a congruent alternate timeline to determine that three tachyon pulses were converging on the center of the eruption, ultimately acting as its cause.

- Tomographic imaging is, in fact, already in significant use in industry and medicine. It is designed to display distinct sections or slices of its subject. How the scanner relates to the field in use today was not revealed in the episode.
