Abstract: A multifunction gamma radiation detector includes a supporting rod, a detection head coupled to or integrated with a first end of the supporting rod including detection elements separate from each other for simultaneously detecting gamma radiation directed along respective directions. Each detection element includes a scintillation crystal and corresponding first electronic conversion circuitry for receiving an optical signal from the crystal and converting it into an electrical signal. The detector also includes a handgrip, connectable to a second end of the supporting rod and which can be manually gripped by an operator to direct the detector, and a second electronic circuitry for converting and/or treating the signals connected to the first electronic conversion circuitry. The head also includes an optical detection device acquiring a sequence of optical signals emitted by a suitably energized body tissue. The detection elements are angularly distributed on the detection head about optical detection device.

Abstract: Described is a directional gamma detector including a detection probe and a handgrip, wherein the detection probe includes: a supporting rod and a detection head coupled or integrated with a first end of the supporting rod. The detection head includes a plurality of detection elements distinct from each other for simultaneously detecting gamma rays directed in different directions and including at least one scintillation crystal and a corresponding first electronic conversion circuitry. Each detection element is associated with a respective collimator. The handgrip is equipped internally with a second electronic circuitry for converting the signals. The detection probe, and in particular a second end of the supporting rod, is reversibly connectable to the handgrip by a mechanical connector equipped with electrical contacts for transferring the signals from the first electronic conversion circuitry to the second electronic conversion circuitry.
