Continuous moisture getter for solid state detector

Abstract

A nuclear camera system () includes a gantry () disposed about an examination region () having detector heads () mounted to the gantry. The detector heads () include an enclosure () defining a volume (). A plurality of solid state detectors () are arranged in an array () within the enclosure volume. A first cold plate () is in thermally conductive contact with the plurality of solid state detectors. A first Peltier cooler () is in thermally conductive contact with the first cold plate, the first Peltier cooler provides for cooling the plurality of detectors in the array. A second cold plate () is located within the enclosure and is thermally insulated from first cold plate. A second Peltier cooler () is in thermally conductive contact with the second cold plate, the second Peltier cooler for removing moisture from the volume (). A heat sink () is in thermally conductive contact with the first and second Peltier coolers. A sensor () is in operative relationship with the detector head. The sensor () provides a signal indicative of an environmental condition within the interior volume of the detector head. A controller () is controllably connected to the sensor. The controller determines a modification, modification in response to the sensor signal, to a selected environmental condition within the interior volume of the detector head and provides a control instruction for the modification. An actuator () is in operative relationship with the interior volume of the detector and is controllably connected to the controller. The actuator implements a control instruction from the controller for modifying the selected condition within the detector head.
