GANGED DETECTOR PIXEL, PHOTON/PULSE COUNTING RADIATION IMAGING DEVICE

摘要

A ganged-detector pixel cell is used in a device having an array of such pixel cells to construct an x-ray and gamma-ray radiation energy imaging device. The ganged detector pixel cell comprises a detector pixel array of two or more detectors pixels disposed on a semiconductor detector substrate. The detector pixels of the pixel array are in electrical communication with a single pixel signal counting circuit disposed on an adjacent ASIC readout substrate. The ganged-detector pixel cell has a Ratio of Correspondence (RC) between of the number of pixel detectors to the single pixel signal counting circuits in the cell of RC>= 1. In practice, the Ratio of Correspondence between of the number of pixel detectors to the single pixel signal counting circuits in a pixel cell is RC >= 2.
