The detection of annihilation photons in positron emission tomography (PET) is based on scintillation light detection, but an interesting alternative Cherenkov photons. Dense radiators provide opportunity for high gamma efficiency—due to their stopping power and photofraction—and excellent coincidence time resolution (CTR). However, because only a few tens follow interaction the radiator, effic...
Faculty of Applied Sciences, Delft University of Technology, Mekelweg 15, Delft, 2629 JB, the Netherlands Time-of-flight Positron Emission Tomography (TOF-PET) and TOF-PET/MRI require scintillators with high light yield, short decay time, and short rise time in order to obtain high timing resolution. LSO:Ce and LYSO:Ce are commonly used. Ca co-doped LSO:Ce shows improved scintillation propertie...
UNLABELLED The aim of this study was to evaluate the imaging performance of 39- and 52-ring time-of-flight (TOF) PET/CT scanners. We also assessed the potential of reducing the scanning time using a 52-ring TOF PET/CT scanner. METHODS PET/CT scanners with 39- and 52-ring lutetium oxyorthosilicate detectors were evaluated. The axial fields of view were 16.2 and 21.6 cm, respectively. We used a...
