<P>PROBLEM TO BE SOLVED: To provide a computerized method and apparatus for improving diagnostic precision using intensified images for detecting interval changes between temporally sequential digitized medical images. <P>SOLUTION: A pair of images are digitized (steps 10, 20) and then subjected to image registration including non-linear warping of one of the images so that corresponding locations in the two images are aligned with each other (step 40). Subsequent to image registration, a subtraction process is performed on the warped image and the other image (step 50). In this manner, slight opacities which are only present in the later image, may be detected in a subtraction image. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
