Abstract :
The monolithic scintillator block, read out by an APD array, is a very promising detector concept for PET. Some recent results demonstrating this are presented. Furthermore, using experimental information, we performed a simulation study of the position resolution of the monolithic blocks as a function of gamma-ray energy. The best resolution is obtained in the 140 –250 keV region, i.e. for 99mTc and 111In, while at 364 keV (131I) the resolution is still good. Consequently the monolithic block approach can also be applied for SPECT. We discuss a combined PET/SPECT system employing monolithic scintillator block detectors.
