An alignment apparatus and a program that improve the accuracy of alignment between two radiation images are provided. For each of portions of the two radiation images, evaluation means calculates an evaluation value that evaluates an amount of positional shift regarding a tissue radiographed in the radiation images, and search condition setting means sets for each of the portions a condition of search for corresponding positions between the two radiation images based on the evaluation value. According to the search condition having been set, alignment means searches for the corresponding positions between the two radiation images, and aligns the two images by warping at least one of the radiation images.
