Recent Advances and Future Progress in PET Instrumentation

PET is an important and growing imaging modality. PET instrumentation has undergone a steady evolution improving various aspects of imaging. In this review, we discuss recent and future software and hardware technologies for PET/CT. The improvements include new hardware, incorporating designs with digital photomultipliers, and fast electronics, allowing implementation of time-of-flight reconstruction. Manufacturers also improved PET sensitivity with a larger axial field of view and 3D imaging. On the CT side, faster scanners and multislice detectors allow implementation of advanced acquisition protocols such as 4D CT and coronary CT angiography.
