note = "Funding Information: There currently are 2 operational long AFOV PET scanners: the uEXPLORER, codeveloped by the University of California, Davis (UC Davis), and United Imaging Healthcare (Shanghai, China) and the PennPET Explorer, designed and built at the University of Pennsylvania (UPenn). Both of these efforts were supported through the EXPLORER consortium, which was set up in 2011 to develop long AFOV PET scanners and funded by the National Institutes of Health in 2015. In designing both of these systems, the goal was to maintain the performance of standard AFOV clinical PET scanners (eg, spatial, timing, and energy resolutions) while extending the AFOV in order to explore the potential benefits and applications of these long systems. The optimal AFOV and scanner design is as yet undetermined. Having 2 systems of different designs allows for probing the impact of design characteristics on clinical performance. Table 2 summarizes the performance characteristics of the 2 systems. Funding Information: This work was funded by the National Institutes of Health under grants R01 CA206187 and R01 CA113941.",
