Abstract: A planar-symmetry device for high-sensitivity gamma ray detection, which allows real-time tomography image reconstruction with very good spatial resolution. Advantageously, the multi-pinhole collimators of the device move during data collection and/or one or more of the pinholes thereof moves independently, thereby allowing possible artifacts resulting from overlap areas of the detector to be completely eliminated.

Abstract: A device for the detection of gamma rays presents a high resolution in the three-dimensional position of the impact of the gamma ray within one or more scintillation crystal blocks coupled to an array of photosensors, for the determination of the impact energy of said gamma ray, the determination of the instant in time when said impact occurred, the interaction depth and the determination of the time-of-flight. Advantageously, in said device, the scintillation crystal detection blocks are optically isolated, in such a way that the scintillation light can only exit said blocks via the output region; and the scintillation crystal detection blocks and the array of photosensors are disposed in direct optical coupling.

Abstract: The invention relates to a device for the detection of gamma rays coming from a source without image truncation and without image overlapping, comprising, at least, two detection cells and each of said cells comprising a detection space adapted to receive the gamma rays that penetrate through an opening, wherein said detection space comprises one or more detection assemblies, with some of said assemblies being positioned such that they stand in the way of the gamma rays coming into the overlap volume thereof.

Abstract: The present invention relates to a method for the detection of gamma rays with the capacity to determine multiple interactions and the corresponding time sequence thereof. The method utilizes a device having: one or more detection means for detecting the energy load qi deposited on the coordinates (x, y, z) of a detecting element and the time instant ti corresponding to the detection of said deposition; electronic data reading and acquisition means connected to the detection means of the device, said electronic means being configured for capturing, digitizing, and transmitting the detection signals of the device; and at least one processing unit connected to the electronic means, configured with software and/or hardware means for recording and/or processing data generated by the electronic data reading and acquisition means.
