Abstract :
Genisys4 is a new preclinical positron emission tomography (PET) scanner, which consists of four detector panels. Due to its unique design, the performance characteristics of the system is different from the conventional multiple detector ring preclinical PET scanners. In this paper, we compare the performance of the four-panel Genisys4 with two ring-geometry scanners: microPET R4 and Inveon. For this purpose, a NEMA NU 4-2008 image quality phantom and two mice injected with 18F-FDG were scanned. The results will aid investigators in using the appropriate PET scanner for their preclinical studies.
