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.

Abstract: One example method to improve image quality of projection image data may include obtaining projection image data and channel offset data associated with the projection image data. The channel offset data may be acquired using the flat panel detector and include at least one set of channel offset data values associated with respective channels of the flat panel detector. The method may also include generating channel offset drift data representing one or more variations of the channel offset data from a reference channel offset data. The method may further include generating offset-compensated projection image data by modifying the projection image data based on the channel offset drift data to compensate for the one or more variations of the channel offset data.

Abstract: Circuitry and method for collecting image array data in which pixels are addressed and dynamically clamped separately. In accordance with one embodiment, pixels are addressed and clamped during different time intervals, thereby allowing faster pixel data readout while still allowing sufficient time to remove all pixel charges.

Abstract: An image acquisition device employs a low-Z material to maximize the probability of backscattering or direct hits in Compton scattering for radiation with a given energy spectrum that passes through a detector array to enhance the contrast and spatial resolution of the image acquisition device. A radiation apparatus including the image acquisition device is also provided.
