Abstract:
1. A detector for a radiation imaging device having at least one of a KV radiation source for providing KV imaging and an MV radiation source for providing MV imaging, comprising: a photodetector assembly for detecting light, the photodetector assembly having a first side and a second side; a scintillator disposed adjacent to the first side of the photodetector assembly for receiving radiation and producing light detectable by the photodetector assembly; and a metal plate disposed adjacent to the second side of the photodetector assembly for attenuating radiation having an energy in the megavolt (MV) range, wherein the first side of the photodetector assembly is positioned toward the KV radiation source for KV imaging and the second side of the photodetector assembly is positioned toward the MV radiation source for MV imaging.
