Abstract

An imaging device includes: a scintillator layer; and an array of photodiode elements; wherein the scintillator layer is configured to receive radiation that has passed through the array of photodiode elements. An imaging device includes: a scintillator layer having a plurality of scintillator elements configured to convert radiation into photons; and an array of photodiode elements configured to receive photons from the scintillator layer, and generate electrical signals in response to the received photons; wherein at least two of the scintillator elements are separated by an air gap. An imaging device includes: a first scintillator layer having a plurality of scintillator elements arranged in a first plane; and a second scintillator layer having a plurality of scintillator elements arranged in a second plane; wherein the first scintillator layer and the second scintillator layer are arranged next to each other and form a non-zero angle relative to each other.
