Abstract
In this thesis we present the R&D of a Compton Camera (CC) for small object imaging. The CC concept requires two detectors to obtain the incoming direction of the gamma ray. This approach, sometimes named ``Electronic Collimation,'' differs from the usual technique that employs collimators for physically selecting gamma-rays of a given direction. This solution offers the advantage of much greater sensitivity and hence smaller doses. We propose a novel design, which uses two similar Position Sensitive Photomultipliers (Hamamatsu 8500) coupled to different scintillators (one plastic and one inorganic). Assets of just one kind of detector are the simplicity of desi...
