Abstract

PURPOSE: To obtain the scintigrams similar to those obtained at even sentivity by providing a data memory device for correctiving the unevenness of the detection sensitivity and performing the correction of display frequencies of bright point so that the sensitivity approximately equal to the minimum position of the detection sensitivity may be obtained.
CONSTITUTION: The incident position of incident γ rays to the detecting face of the detector is calculated from the detection output of the detector 21 and the position signals XS, YS indicating the two-dimensional X, Y axis positions thereof and the luminance signal UNB are outputted from a position calculating circuit 22. The position signals thus outputted are converted to digital values in A/D converters 21a, 23b. Delay circuits 24a thru 24c are connected to the respective signal lines in order to input the position signals and luminance signal with respective specified time delays to the display device. The luminance signal having been sent through the delay circuit 24c is controlled of passage with an AND gate 25 and when the output from the AND gate is obtained, the bright point is displayed in the position determined by the position signals XS, YS in the display device 26. The bright point thus displayed is photographed with a camera 27 and is stored in a film, whereby the scintigram is obtained.
