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.
