Abstract
PURPOSE:To reduce the end effect of a radiation position detector and widen an effective visual field with relatively simple constitution by reading only an output from the end part of the radiation position detector independently, and performing the incidence position arithmetic of a center part and a peripheral part individually. CONSTITUTION:A position arithmetic circuit 1 passes outputs OUT1-OUT4 from the radiation position detector 2 through amplifier 3a-3d and gate integrators 4a-4d and then position computing elements 5a-5c performs position arithmetic operation individually to output arithmetic results P1-P3. Then when a signal is inputted to the end part of the detector 2, a comparator 6 sends an arithmetic result P1 (or P2) as a comparison result to a selector 7, which selects the arithmetic result P1 (or P2) to obtain a position output signal DT. Consequently, the end effect of the end part of the detector 2 is reduced and the position of signal input to the end part is also detected with accuracy.
