Abstract :
A nuclear medicine gamma camera (Siemens HD3) has been characterized for use as a gamma spectrometer over an energy range of 30–690 keV. To our knowledge, there is no other published data on the behavior of commercial gamma cameras over this complete energy range. Low activity γ-sources (109Cd, 57Co, 133Ba, 22Na, and 137Cs) were used to calibrate the system energy response, linearity and resolution, at 88, 122, 356, 511, and 662 keV, respectively. The gamma camera characterized is a typical commercial imaging system.
