Title:
GANGED DETECTOR PIXEL, PHOTON/PULSE COUNTING RADIATION IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO2004008488
Kind Code:
A3
Abstract:
A ganged-detector pixel cell is used in a device having an array (100) of such pixel cells to construct an x-ray and gamma-ray radiation energy imaging device. The ganged detector pixel cell (105) comprises a detector pixel array (100) of two or more detectors pixels (110) disposed on a semiconductor detector substrate (112). The detector pixels (110) of the pixel array (100) are in electrical communication with a single pixel signal counting circuit (130) disposed on an adjacent ASIC readout substrate (132). The ganged-detector pixel cell (105) has a Ratio of Correspondence (RC) between of the number of pixel detectors (110) to the single pixel signal counting circuits (130) in the cell of RC>= 1. In practice, the Ratio of Correspondence between of the number of pixel detectors (110) to the single pixel signal counting circuits (130) in a pixel cell is RC >= 2.
