Abstract
A radiation imaging device has a plurality of scintillator elements that are each optically coupled to a plurality of internal gain photodetectors. Each photodetector is electrically coupled to a respective detect and hold circuit which amplifies and stores the pulse generated by the photodetector; the stored pulses are sampled via a multiplexed switching arrangement to allow the stored signal from each detect and hold circuit to be processed to produce a digitized imaging signal which corresponds to the energy level of, and location on the array of, the detected incident radiation. The digitized imaging signal is supplied to display memory and analysis equipment for the device.
