An all-digital positron emission tomography (PET) scanner for imaging small animals has been developed at Huazhong University of Science and Technology (HUST). The implementation of block detector with position sensitive photomultiplier (PSPMT) and multi-voltage threshold (MVT) technology is presented in this paper. The detector comprises 12 basic detector modules (BDMs), which can be used to construct...
All digital Positron Emission Tomography (PET) has such potential advantages as quick and efficient calibration, achieving the ideal timing resolution for time of flight (TOF) PET imaging and specific application aiming at requirements. To improve the pulse processing in digital PET, we continue the pulse shaping method which decreases the speed of Analog to Digital Converter (ADC) sampling and facilitates...
