A GAMMA SOURCE TRACKING SYSTEM

摘要

The invention relates to a radioactive source tracking system adapted to determine in real time a spatial position of a gamma source (la, lb) in a volume, comprising a set of spatially distributed position sensitive detectors (PSD) (5) operable in real time arranged about the volume, a real time computer system adapted to calculate the spatial position per time stamp of the gamma source in the said volume based on respective signals generated by said PSD's, wherein the radioactive source is represented by a 3D or 4D data stream in real time. The invention further relates to a method for tracking a radioactive gamma source and a computer program product for causing a processor to determine a real time 3D or a 4D spatial position of a gamma source.
