Response functional creation device and radiation detection position discrimination device for radiation detection position discrimination of radiation detector

摘要

When with the radiation detector which is formed from the scintillator and the light absorbent component which internalize the optical discontinuous dot, irradiating radiation to the aforementioned radiation detector evenly in the luminous position operation technique inside the aforementioned scintillator which uses the response function of aforementioned light absorption component output, to calculate the presumption luminous position inside each scintillator block from the measurement result, by the aforementioned optical discontinuous dot to select the multiple events where radiation causes interaction in the presumption luminous position inside the said scintillator, adding averaging aforementioned light absorption component output vis-a-vis the event radiation operation mutually at luminous position inside the same scintillator, aforementioned response functionIt creates. Because of this, the necessity precision to move the collimator and the gamma line source well is gone, it becomes possible to compact the measuring time of response function. In addition, like the DOI detector and the crystal cube detector which until now are difficult even with the detector which has length in depth direction it reaches the point where it can create response function easily.
