A apparatus particularly well suited for use in medical imaging includes radiation sensitive detectors () which detect gamma radiation indicative of radionuclide decays in an examination region (). The detectors () are supported by generally c-shaped support () for rotation about a detector rotation axis (). The support () is farther attached to a pivot joint () which allows adjustment of the detector rotation axis (). The support () may also be translated in two degrees of freedom to so that the detectors () orbit the examination region () in a non-circular orbit.

Gantry system

A radiation detector package includes a radiation-sensitive solid-state element () having a first electrode () and a pixelated second electrode () disposed on opposite principal surfaces of the solid-state element. An electronics board () receives an electrical signal from the solid-state element responsive to radiation incident upon the radiation-sensitive solid-state element. A light-tight shield (') shields at least the radiation-sensitive solid-state element from light exposure and compresses an insulating elastomer and metal element connector () between the pixilated electrode () and contact pads () on the electronics board.

Solid state detector packaging technique

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.
