Abstract
Disclosed are a method and apparatus for producing a real-time electronic signal which represents a radiation image. The apparatus includes a source of radiation which bombards a human or other body being examined and produces a radiation image. The radiation image strikes a luminescent phosphor screen thereby ionizing the phosphor and storing information therein which indicates the intensity or total quantity of the ionizing radiation. A scanning laser beam having a high intensity beam is used to very rapidly stimulate the phosphor screen. An emission detector measures the intensity or total quantity of emission from the phosphor screen and creates an electronic signal. The electronic signal is synchronized with information about the position of the scanning laser beam and the delay associated with the phosphor stimulation. An electronic video signal is thereby produced which can be displayed on a conventional video display, recorded or digitized for storage, analysis and enhancement with computers.
