RADIATION DETECTION AND METHOD FOR NON-DESTRUCTIVE MODIFICATION OF SIGNALS

摘要

A radiation detector, comprising: a scintillator layer; an array of active pixel sensors (APS); at least one internal temperature sensor coupled to at least one pixel; at least two feedback circuits embedded into each pixel; processing electronics configured to allow sampling of said electrical signals by the at least two feedback circuits, and configured to allow corrections corresponding to the measured temperature such that a clean image is produced; and an internal memory unit coupled to the array of APS, and configured to allow storage of correction parameters and of at least two images corresponding to the array of pixels, wherein the radiation detector is configured to acquire at least two images, corresponding to the at least two feedback circuits, and wherein the radiation detector outputs a single, merged image.

1. A detector for detecting radiation, comprising:
a scintillator layer configured to allow conversion of the radiation into optical signals; an array of active pixel sensors (APS) positioned adjacent to the scintillator layer such that the optical signals are detected by the array of APS, and configured to allow conversion of the optical signals into electrical signals; at least one internal temperature sensor coupled to at least one pixel of the array of APS, the at least one internal temperature sensor providing measurement of temperature; at least two feedback circuits embedded into each pixel of the array; processing electronics configured to allow sampling of said electrical signals by the at least two feedback circuits, and configured to allow corrections corresponding to the measured temperature such that a clean image is produced; and an internal memory unit coupled to the array of APS, and configured to allow storage of correction parameters and of at least two images corresponding to the array of pixels, wherein the radiation detector is configured to acquire at least two images, corresponding to the at least two feedback circuits, and wherein the radiation detector outputs a single, merged image.
