digital fluoroscopy,
the projection of a radiographic image on an image-intensifying fluorescent screen coupled to a digital video image processor. The screen has an input surface coated with a phosphor that is twice as sensitive to x-rays as conventional x-ray film. The visible light from the energized phosphor is electronically amplified and directed into a video camera. The video image is divided into pixels, which are in turn converted or digitized for storage or reproduction through an image processor. Want to thank TFD for its existence?
