摘要:
An imaging system includes a scintillator array (202) and a digital photomultiplier array (204). A photon counting channel (212), an integrating channel (210), and a moment generating channel (214) process the output signal of the digital photomultiplier array (204). A reconstructor (122) spectrally resolves the first, the second and the third output signals. In one embodiment, a controller (232) activates the photon counting channel (212) to process the digital signal only if a radiation flux is below a predetermined threshold. An imaging system includes at least one direct conversion layer (302) and at least two scintillator layers (304) and corresponding photosensors (306). A photon counting channel (212) processes an output of the at least one direct conversion layer (302), and an integrating channel (210) and a moment generating channel (214) process respective outputs of the photosensors (306). A reconstructor (122) spectrally resolves the first, the second and the third output signals.
