Résumé
To investigate the minimum number of SiPM detectors required for solid-state digital photon counting (DPC) oncologic whole-body 2-deoxy-2-[ A DPC PET/CT (Vereos, Philips) with 23,040 1-to-1 crystal-to-detector couplings was utilized. [ One hundred twelve lesions (d = 10 to 95 mm) were analyzed in the patient population. All lesions remained visible and were demonstrated without compromised image quality under all BMIs in the 50 % sparse detector configurations despite the DPC PET system sensitivity reduction to 1/4th. An excellent consistency of SUV The feasibility of either expanding the axial field of view (FOV) by a factor of two or halving the number of detectors was demonstrated for solid-state digital photon counting PET, thus either potentially enabling cost reduction or extended effective axial FOV without increased cost.
