- 摘要：
PROBLEM TO BE SOLVED: To provide a technique which enables the acquisition of a better image by minimizing the generation of artifact in a radiation measuring apparatus.
SOLUTION: The values of pixels detected with amplification rates different so much as to cause a level difference in images are corrected using the ratio of the amplification rates (gain ratio) calculated from actual measurement data. The positions at which the amplification rates are changed are extracted as switching positions and the values pertaining to the changeover position are calculated separately from the measurement data on both sides of each switching position to compute the gain ratio using both the values pertaining to the switching position calculated.
