Abstract
A semiconductor coincidence detector device including at least a first and a second detector crystal array, each having a first and second surface, an array of pixellated anodes formed on each of the first surfaces, an array of segmented cathodes formed on each of the second surfaces, essentially each of the pixellated anodes being connected to an anode electronic channel for generating a first electrical signal corresponding to the energy of a photon impinging in the semiconductor, and essentially each of the segmented cathodes being connected to a cathode electronic channel for generating an electrical coincidence trigger signal on detection of a photon impinging in the semiconductor, the first electrical signal being read only from anodes located opposite the cathode segment generating the trigger signal.
