A brain image normalization device, method, and program that make it possible to normalize a brain and anatomical structures in the vicinity of the brain. According to the present invention, a landmark detection unit 22 detects, from a brain image B0, at least four reference landmarks from among the left eye, the right eye, the diencephalon, the fornix, the corpus callosum, the left hippocampus, and the right hippocampus. An alignment unit 23 aligns the reference landmarks detected by the landmark detection unit 22 and reference landmarks in a standard brain image Bs that correspond to the detected reference landmarks. A normalization unit 24 normalizes the brain image B0 on the basis of the results of the alignment.
