Abstract:
1. A solid state x-ray detector comprising: a monolithic x-ray detecting element having a front and rear surface; at least one electrode attached to the front surface of the monolithic x-ray detecting element; a plurality of electrodes attached to the rear surface of the monolithic x-ray detecting element and electrically separated by gutter regions, wherein the electrodes define areas corresponding to pixels in a reconstructed image and the gutter regions define areas where charge carriers are able to migrate unpredictably toward one of a variety of areas corresponding to one of a variety of pixels in the reconstructed image; and an x-ray blocking mask attached to the front surface of the monolithic x-ray detecting element and having openings arranged opposite the plurality of electrodes on the rear surface and blocking elements arranged over the gutter regions to substantially block x-rays directed toward the front surface of the monolithic x-ray detecting element from entering an area on the front surface of the monolithic x-ray detecting element opposite the gutter regions.
