ABSTRACT:
The invention comprises a scintillator for converting impinging x-rays into visible light; a sensor array having two opposed surfaces with a plurality of detectors at one of the surfaces and having the other of the surfaces facing the scintillator; and a plurality of processing circuits facing the one surface and connected to the detectors by bump bonds. Another feature of the invention is a gain stage in close proximity to sensors, which may be MOS capacitors. A single gain stage may be connected to one capacitor or may be connected to several at one time.
