Abstract: Some embodiments include transmission of a pulse to imaging elements in order to read an image frame from the imaging elements, prior to exposure of the imaging elements to radiation that is to be converted to and captured as image data, wherein the pulse is transmitted so that the image frame is read and the imaging elements become ready to capture image data associated with the radiation substantially immediately before the imaging elements are exposed to the radiation.

Abstract: X-ray therapy EPI artifact reduction and control of imaging is provided. Scanning of images is synchronized with the pulse rate of the x-rays. The scanning period is longer than the pulse rate period, so artifacts are generated within the resulting images. Due to the synchronization, the pulse variation artifacts are aligned across multiple images. The synchronization and resulting alignment of linear artifacts allows for gain correction as a function of lines within the image. Such gain correction reduces or removes non-linearities associated with pulse rate variation.

Abstract: A system for determining congruence of a light field and a radiation field includes acquisition of first electronic image data representing a phantom as illuminated by light emitted by a light emitter, acquisition of second electronic image data representing the phantom as irradiated by treatment radiation emitted by the treatment radiation emitter, and determination of congruence of a light field produced by the light emitter and a treatment radiation field produced by the treatment radiation emitter based on the first electronic image data and the second electronic image data.

Abstract: An x-ray imaging system includes a praseodymium (Pr) doped gadolinium oxysulfide (Gd2O2S) scintillator and a detector array positioned adjacent to the scintillator. The scintillator is particularly suited for x-ray imaging applications in which fast scan times are desired.

Abstract: System and method aspects for a photoconductive element for a radiography imaging system are described. The photoconductive element includes a conducting layer for absorbing photons generated indirectly from radiation passing through an object being imaged by the radiography imaging system. Also included is an interdigital contact structure in the conducting layer.
