Abstract:
1. A Tomographic Radiation Imaging System, without collimators, for detecting the positions of sources of gamma or X-rays hereinafter referred to as electromagnetic radiation, comprising: a) track detectors for registering tracks of electrons created by the interaction of the electromagnetic radiation with said track detectors wherein said track detectors comprise: b) position sensitive detectors of electromagnetic radiation, and c) photo-detector digital Cameras hereinafter referred to as Cameras, wherein d) Camera readout electronics for identifying the photo-detector pixels that, within a predetermined time window, generate an electric signal following a scintillation event, and e) time coincidence circuits for correlating separate tracks in the track detector and signals detected by the position sensitive detectors, and f) an electronics interface containing position electronics for registering in real time the absolute position and direction of the Radiation Imaging System, the coincidence circuits, the readout electronics of the Photodetector cameras, temporary memory and communication means for relaying the outputs of the Cameras to an external computer for building a Tomographic image of the Radiation sources.
