1. A medical image registration method performed by a medical image registration apparatus, the method comprising:
generating a two-dimensional rigid image obtained by two-dimensionally projecting rigid tissue segmented from a three-dimensional medical image;
generating a two-dimensional soft image obtained by two-dimensionally projecting the three-dimensional medical image or a two-dimensional soft image obtained by two-dimensionally projecting soft tissue segmented from the three-dimensional medical image;
registering a two-dimensional medical image with the two-dimensional rigid image;
registering the two-dimensional medical image with the two-dimensional soft image, and
segmenting a lesion region from the three-dimensional medical image;
generating a two-dimensional lesion image obtained by two-dimensionally projecting the lesion region;
generating a lesion registration image by applying, to the two-dimensional lesion image, values for translating, rotating, or scaling previously applied to the two-dimensional soft image for registration between the two-dimensional medical image and the two-dimensional soft image; and
superimposing and displaying the lesion registration image on the two-dimensional medical image.
