Detector systems for integrated radiation imaging

An integrated CT-Compton-PET detector imaging system comprising:

• two or more layers of edge-on detector modules irradiated from a side and having a substrate positioned edge-on to at least one of x-ray photons from an x-ray radiation source or gamma ray photons from a gamma ray radiation source, incident thereon;
• electronics configured for tracking interactions of the x-ray photons and the gamma ray photons and analyzing the readout signals using at least one of energy integration or photon counting or photon counting with energy resolution techniques;
• and
• an electronic communications link to a computer configured for post-processing, storage, and display of radiation image data generated thereby;
• wherein the detector imaging system is configured as a CT detector imaging system and a Compton-PET detector imaging system configured to function independently, with a CT-PET detector imaging system having one or more layers of the edge-on detector modules, and the CT detector imaging system having one or more layers of the edge-on detector modules, and
