1. An image processing apparatus comprising processing circuitry configured:
to obtain three-dimensional image data of a brain acquired by performing a magnetic resonance imaging process, the three-dimensional image data being image data of a T2*-weighted image, a phase map, a magnetic susceptibility image, a magnetic susceptibility weighted image, a T2* image, or a R2* image;
to generate a projection image in which a surface of a cross-section of at least a part of the brain is aligned on a plane and a micro bleed or calcification occurring in the brain is rendered, by performing a projecting process on the three-dimensional image data in a range limited on a basis of a shape of the brain; and
to output the projection image.
