Fig. 1From: Performance evaluation of the next generation solid-state digital photon counting PET/CT systemSolid-state digital photon counting PET detector design. When a scintillation photon hits the microcell sensor, the integrated photon counter increases and the integrated timer measures the arrival time of the individual photon on that die. The chip measures all photons during the desired duration of the detection process. The values of the integrated photon counter and timer are read out via a digital interfaceBack to article page
