Abstract: A mechanical collimator receives particles from a gamma radiation emission source and/or neutron emission source, a material that absorbs neutrons and is virtually transparent to gamma radiation A first detector includes a scintillator crystal with neutron-gamma discrimination capability and a position-sensitive photosensor, coupled to the mechanical collimator. One or more detector blocks have scintillator crystals of gamma or neutron-gamma radiation and position-sensitive photosensors, after the first detector, on a face opposite the mechanical collimator. A processing and acquisition module is connected to the detectors The device is suitable for use in inspections relating to nuclear safety, port safety, nuclear threats and accidents, and hadron-therapy treatments and nuclear medicine.

Abstract: The present invention relates to a system (10) and method for the volumetric and isotopic identification of the spatial distribution of ionizing radiation from point or extensive radioactive sources (3) in radioactive surroundings. More specifically, this system (10) comprises a gamma radiation detector (2) and an optical transducer (1) joined to each other and linked to a control unit to detect the absolute position of radioactive sources (3) relative to a visual reference located in the radioactive surroundings, and to determine the radioactive activity of the sources, that is to say it detects the isotope composition of the radioactive sources (3).

Abstract: The present invention relates to a dual image system, suitable for oncological diagnoses and real time guided biopsies, comprising: an ultrasound imaging device (1) for obtaining associated signals with one or more anatomical images; a gamma ray detector (2) for obtaining associated signals with one or more functional images; an electronic module (3) for processing the obtained signals by the detectors (1, 2); a casing (4) housing the detectors (1, 2); characterized in that the gamma ray detector (2) is a gamma ray Compton scattering detector, comprising at least two individual gamma detectors (2a, 2b) substantially aligned in the same detection direction and with the detection surfaces substantially parallel to each other; the ultrasound imaging device (1) and the gamma ray detector (2) have the same detection directions substantially aligned with each other.
