Claim:
1. A detector array, comprising: at least one detector pixel that includes photosensitive regions of a photosensitive layer arranged to define and include a cavity of a three dimensional volume, wherein surfaces of the cavity include at least two photosensitive regions and a non-photosensitive region there between, defining at least two sub-pixels which detect light photons traversing within the three dimensional cavity and produce respective signals indicative thereof, wherein the cavity includes photosensitive surfaces of each of the at least two photosensitive regions that join with an angle of at least one of a group consisting of a perpendicular angle and an oblique angle; and a scintillator, including a first sub-portion that is located within the cavity and which emits the light photons in response to absorbing x-ray photons, wherein light photons emitted by the first sub-portion are detected by both of the at least two sub-pixels.
