Title:
Use of a central positron emitting reference source to improve the timing alignment of a singles list-mode small animal PET scanner 
Abstract:
To minimize the system-wide timing resolution of a PET scanner, and hence the applied coincidence window, a delay must be added to the signals from each crystal to compensate for inherent time differences between detectors. Without an absolute time reference, this must be been done iteratively. We propose using a new timing probe, consisting of a Ge-68 source imbedded in a plastic scintillator coupled to a fast PMT, to time-calibrate the MADPET-H small animal PET scanner. The probe provides a pr...    »
