We developed a modular and scalable PMT-based detector for a Time-of-Flight PET system. The detector is divided into 5 segments. The position within each segment is determined by applying Anger logic to 4 PMTs which read out the segment and using a crystal look-up table (LUT) to convert the position to a specific crystal location. Routine quality controls (QC) are necessary to keep the system performance...
Adding time-of-flight (TOF) technology has been proven to improve image quality in positron emission tomography (PET). In order for TOF information to significantly reduce the statistical noise in reconstructed PET images, good timing resolution is needed across the scanner field of view (FOV). This work proposes an accurate, robust, and practical crystal-based timing calibration method using ${}^{18}{\rm F} - {\rm FDG}$...
