A radiation detection system comprises a scintillator for converting radiation to visible light; two buttable CMOS wafers; an adjacent acquisition board, for acquiring pixel values; and a processing board for detecting image edge is described. The butt of each adjacent CMOS wafers pair is made such that the total width of two peripheral pixel lines and the spacing between them sums to a whole number of pixel pitch.

X-ray radiation detector with automatic exposure control

An apparatus and method for radiation detection is herein described. The apparatus consists of two radiation-detection arrays: A primary radiation-detection array, based on scintillator-CMOS design, and a secondary radiation-detection array, mounted on the back of said primary array. A method of controlling the detection operation is described, where output of the secondary array is exploited for controlling the acquisition-start and acquisition-stop of the primary array. Further, the apparatus is equipped with fast memory for storage of correction tables, and with a processor for fast computation of the correction. A method of calibration is also describes with tables for: offset correction, gain correction, and for defect-pixel correction. These tables are evaluated by the fast processor and stored on the fast memory. A method of real-time evaluation of the signal corrections is described, which depends on the acquisition-start and acquisition-stop timings and which results a clean, artifact-free image.
