PROBLEM TO BE SOLVED: To analyze a motion of a subject based on at least two images produced by a tomographic device at two consecutive times by use of a simple means in an improved form compared to known methods. SOLUTION: The method is for analyzing a motion of a subject based on at least two images formed by a tomographic device at two consecutive times. In an image range selected along an edge from each of the two images, a vector field is formed, and a displacement vector is determined to represent displacement of local image information between the first image and the second image. At least one divergence value is computed from the vector field for analyzing the motion. COPYRIGHT: (C)2007,JPO&INPIT
