What does the acronym CRT stand for in medical imaging?

In medical imaging, the acronym CRT stands for Cathode Ray Tube. This technology has historically been significant in the evolution of imaging devices, especially in the context of older display technologies such as televisions and computer monitors used for medical imaging.

Cathode Ray Tubes function by using an electron gun that fires electrons onto a phosphorescent screen, creating images by controlling the intensity of the light emitted. While CRTs have largely been replaced by more advanced technologies like LCD and LED displays in modern medical equipment, their principles were foundational in the development of imaging modalities.

Understanding the role of CRT in medical imaging helps shed light on the historical context of imaging technologies and their progression to current practices.
