<P>PROBLEM TO BE SOLVED: To provide a radiation examination system capable of improving reproducibility of a tomographic image or a stereoscopic image for an analyte, while shortening an examination time. <P>SOLUTION: An image correction device 15: checks a radiation intensity distribution obtained from a radiation detector 2 when moving a radiation source 1 to any target position during a first scan, and a radiation intensity distribution obtained from the radiation detector 2 when moving the radiation source 1 to the same target position during a second scan; calculates a shift amount of a part in which the radiation intensity distributions should overlap; calculates an error of the focal position of the radiation source 1 based on the shift amount; and corrects a plurality of transmission images P based on the error. <P>COPYRIGHT: (C)2012,JPO&INPIT |
