Claim Text:
1. A photon/energy identifying radiation imaging device comprising: a detector substrate having a two dimensional array of radiation detector pixels for detecting incoming radiation events that allows for a count rate determination, in events per pixel per second, of incoming individual radiation events and to identify an energy of each incoming radiation event, said radiation detector pixels convert each incoming radiation event into a single-photon electrical signal; and a readout substrate comprising a two dimensional array of readout pixel circuits coupled to said radiation detector pixels for processing electrical signals respectively corresponding to the single-photon electrical signal of each said incoming radiation events, wherein said readout substrate further comprises both of: wherein each of said incoming radiation events is an individual radiation photon from the group consisting of at least one of x-rays and gamma rays.
