Abstract

A disclosed method includes: defining two first points in a model cross section of a model of an object and two corresponding second points in an image that is a cross section of the object for a reference time; performing first transforming including expansion or reduction for the model cross section so that a position of a second point is identical to a position of a corresponding first point; superimposing the image and the model cross section after the performing; second transforming a second model cross section for a second time after the reference time, so that positions of two second points in a second image for the second time are almost identical to positions of corresponding two first points in the second model cross section; and superimposing the second image and the second model cross section after the second transforming.
