Development of novel low-cost readout electronics for large field-of-view gamma camera detectors
Given the extensive use of gamma cameras as a medical diagnostic instrument for characterizing the biodistribution of gamma-emitting radiopharmaceuticals administered to patients [1 –3], significant research was carried out to improve the performance of gamma cameras [4]. In a gamma camera, first the gamma rays emitted from the patient’s body are collimated using a collimator, subsequently interacting with a monolithic scintillation crystal (commonly used NaI(Tl)). The prod uced light is converted to a signal by an array of large area photomultiplier tubes (PMTs) located on the opposite side of the crystal. (Source: Ph...
