Abstract (in Japanese) (See Japanese page) 
(in English) We propose an automatic calculation method of the degree of non-rigid deformity of the liver in MR Tagging images．In our method，bending energy was calculated，in which the thin-plate splines (TPS) is employed to deform an image using the movement of landmarks (LMs)．Automatic tracing of crossing points of the grid lines in the MR tagging images is developed for searching the LMs．We used MR tagging images of 38 cases with 11 healthy livers and 27 chronic livers in evaluation．Bending energies obtained from the manual trace of the LMs and the automatic trace were compared．The significant difference in bending energies determined from the automatic traces was found between the cases of healthy liver and chronic liver．
