Abstract
A high voltage distribution system for distributing a high voltage supply to a plurality of semiconductor radiation detector modules, includes a conductive strip connected to a high voltage supply. The conductive strip is preferably made of aluminum foil, and contacts a surface of each of the detectors. The conductive strip is held into contact with the semiconductor radiation detectors by applying pressure to said conductive strip with a pressure plate, including a compressible layer such as a foam layer. A vacuum is created in an area occupied by the semiconductor modules and the conductive strip. The high voltage distribution system allows a high negative voltage to be applied to the semiconductor detector modules with a minimum of attenuation. In a preferred embodiment, the detector modules are CZT modules, and the system is incorporated into a solid-state gamma camera for nuclear medicine imaging.
