摘要：

The recent development of CdZnTe detectors has made it possible to produce CdZnTe based clinical radionuclide imagers. We therefore investigate the pixellation geometry ideal for this application using numerical simulation. These studies indicate that, for a fixed pixel pitch, configuring the detector with wide pixel and small interpixel spacing will optimize energy resolution and photopeak efficiency. Other issues concerning the practicality of medical imagers using CdZnTe are also discussed.
