Abstract:
1. A two-dimensional position map correcting method used when detecting with radiation detectors each formed of a plurality of scintillator elements arranged in one dimension, two dimensions or three dimensions, and a light sensor optically coupled thereto, for correcting a two-dimensional position map presenting, in two dimensions, signal strengths obtained with the light sensor as corresponding to incident positions of the radiation incident on the scintillator elements, the two-dimensional position map correcting method comprising a peak separating step for drawing boundaries based on peaks of the signal strengths, and separating respective positions by the boundaries, and a number determining step for determining, by using spatial periodicity of the peaks, the number of peaks having failed to be separated in the peak separating step, with a plurality of the peaks connecting to each other.
