<P>PROBLEM TO BE SOLVED: To provide a radiation foreign matter inspection apparatus for accurately detecting foreign matters mixed into an object to be inspected by preventing the occurrence of erroneous detection, and also to provide a radiation foreign matter inspection method. <P>SOLUTION: A computer 20 for control calculates a degree of congestion in pixels detected as foreign matters contained in a region 32 of interest with all pixels detected as foreign matters as target pixels 31 in an image (first image) after binarization processing. On the basis of the degree of congestion, pixels having a degree of congestion that is equal to or less than a specified threshold are erased from the first image as erroneous detection, pixels that are detected as foreign matters finally are determined, and a second image is formed. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
