Fig. 2From: Technical opportunities and challenges in developing total-body PET scanners for mice and ratsVolumetric resolution and sensitivity at the center of small animal scanners with axial lengths longer than 90 mm [13, 21, 28,29,30,31, 38, 40,41,42,43,44,45,46,47,48], which corresponds to Fig. 1. Only scanners with published results were selected. References of the scanners are shown in Table 3Back to article page
