Illustration of detectors integrated in current TB-PET scanners. a) Detector used in uEXPLORER from United Imaging Healthcare with a 7×6 block of LYSO crystals, each 2.76×2.76×18 mm3, coupled to 4 SensL SiPMs, each 6-mm2, thus relying on a light-sharing scheme for crystal identification (courtesy of Dr. Hongdi Li, United Imaging Healthcare America). b) Detector used in PennPET EXPLORER with an 8×8 block of LYSO crystals, each 3.76×3.76×19 mm3, coupled to the PDPC 64-channel digital SiPM in a 1:to:1 scheme for crystal identification [28].
