<p>An ROI is searched from the center of an image vertically, the band boundary position between a chest area and a band area is determined based on the variation of the average pixel value of the ROI, and image data between an upper band boundary position U and a lower band boundary position L is cut out as chest area data (Step S15). The band boundary of band-including image is automatically detected, and the chest image area is automatically cut out by determining the position of the margin of band-including image based on the variance of the ROI and making the position of the margin the upper or lower band boundary position.</p> |
