Small field of view detectors based on Position Sensitive Photomultiplier Tubes (PSPMTs) have been widely used by many research groups in small-animal imaging and recently clinically in scintimammography. In most cases the PSPMT is coupled to pixelized scintillators since it has been shown that their use improves spatial resolution. The use of a single(More)
SPECT images suffer from low contrast as a result of photons scatter. The standard method for excluding scatter component in pixelized scintillators is the application of an energy window around the central photopeak channel of each crystal cell, but small angle scattered photons still appear in the photopeak window and they are included in the(More)
