Solid state radiation detection panel having tiled photosensitive detectors arranged to minimize edge effects between tiles

摘要

A solid state radiation detection panel adapted to receive radiation, having a plurality of modules positioned immediately adjacent each other, with each of the plurality of modules having an array of photosensitive detectors arranged in a plurality of rows and columns, each of the photosensitive detectors having a radiation sensitive area; and circuit means for selectively addressing one of the photosensitive detectors by addressing one of the plurality of rows and one of the plurality of columns and reading the output of the one of the array of photosensitive detectors where each of the plurality of modules being arranged in a three dimensional structure in which the array of photosensitive detectors is arranged on a planar first surface of the module covering substantially the entire area of the planar first surface. The circuit means is located within the module in an area away from the planar first surface opposite from the received radiation. Photosensitive detectors located along an edge of the module having non-radiation sensitive circuitry located opposite the edge from the radiation sensitive area. The radiation sensitive area of the edge photosensitive detectors are smaller than the radiation sensitive area of the inside photosensitive detectors and the center to center distance of the radiation sensitive area of adjacent photosensitive detectors is maintained substantially constant between adjacent edge photosensitive detectors as adjacent inside photosensitive detectors. The module further has a pin diode along the edge of the module.
