We are developing a 3D positioning positron emission tomography (PET) detector module made up of dense stacks of 0.5 mm × 0.5 mm × 1.0 mm LYSO scintillation crystal elements coupled to position sensitive solid state photomultipliers (PS-SSPMs.) In this work, crystal arrays with four different types of outer face reflectors were tested to investigate the effect of outer reflectors on crystal identification...
In our previous works, we had investigated a pulse width modulation (PWM) based multiplexing readout for a detector that is built from dense stacks of LYSO scintillation crystal elements coupled to position sensitive solid state photomultipliers (PS-SSPMs). In our readout system, each of the PS-SSPM position channel signals are integrated for a set time to obtain event energy and position. In this...
