Solid state radiation detection panel having tiled photosensitive detectors arranged to minimize edge effects between tiles
First Claim
1. A solid state radiation detection panel adapted to receive radiation incident on a first surface of said solid state radiation detection panel, having a plurality of modules having a plurality of edges with at some of said plurality of edges positioned immediately adjacent each other, each of said plurality of modules comprising:
- an array of photosensitive detectors, each representing a pixel, being arranged on a first surface of said module in a plurality of rows and columns coveting substantially said first surface;
said photosensitive detectors located along an edge of said module being designated edge photosensitive detectors and said photosensitive detectors located interior of said module being designated inside photosensitive detectors;
each of said photosensitive detectors having a radiation sensitive area and non-radiation sensitive circuitry associated with one of said photosensitive detectors;
each of said edge photosensitive detectors having said radiation sensitive area located along said first surface nearer said edge of said module than said non-radiation sensitive circuitry.

Abstract
A solid state radiation detection panel 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 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 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 p/n diode along the edge of the module.
