Provided is a technology for obtaining a magnetic susceptibility enhanced image in which it is possible to enhance the contrast difference between a tissue of interest and peripheral tissue regardless of the positional relationship between a static field direction and an imaging cross-section. After converting a phase image into a magnetic susceptibility distribution image that does not depend on the static field direction, the magnetic susceptibility distribution image is used to generate a weighted image used for weighting. In the generated weighted image, the contrast between a tissue of interest and peripheral tissue is enhanced depending on the purpose. Then a magnetic susceptibility enhanced image in which the magnetic susceptibility difference is enhanced depending on the purpose is obtained by crossing the weighted image with an absolute value image.
