ABSTRACT:
A high speed multiple section, computed-tomographic X-ray scanner includes a plurality of radiation detectors arranged in two rings. Each detector comprises an elongated scintillator crystal, a small area photodiode positioned at one end of the crystal, and a light reflector positioned at the opposite end of the crystal with the crystal functioning as a light pipe in directing light to the photodiode. An active low pass filter is employed as a preamplifier for current from each photodiode.
