A system 100 for processing three dimensional (3D) distribution image of a radiation source and a processing method using the same are provided. The system includes an image measuring unit 110 which comprises a plurality of position sensitive detectors to measure the radiation source, the plurality of position sensitive detectors each having a devoted channel set therefore, and being arranged in a circularly fashion around the radiation source, a signal amplifying unit 120 which receives signals indicative of energy magnitude and location of the radiation source from the image measuring unit and amplifies the received signals into an electric signal, a mode selecting unit 125 which receives the electric signal generated at the signal amplifying unit, and selects a detection mode according to the energy magnitude and the location and outputs a corresponding mode signal, a data storage 130 unit which stores the signals indicative of the energy magnitude, time of radiation generation, and location of the radiation source, and the signal received from the mode selecting unit as a series of items, a data converting unit 140 which converts the data stored at the data storage unit into interactive data, an image reconstructing unit 150 which reconstructs the converted data into the 3D distribution image, and a display unit 160 which displays the 3D distribution image received from the reconstructing unit. Depending on the signals, various modes including coincidence mode, single tracking mode of dual gamma ray, coincidence mode/gamma ray tracking mode, and coincidence dual gamma ray tracking mode are implemented to increase efficiency. |
