An image processing apparatus is described herein including an image input unit that receives an input of a tomographic image of a heart imaged from outside a body; a low motion site estimation unit that estimates a low motion site of the heart on the basis of the tomographic image; an infarct site estimation unit that estimates an infarct site of the heart; and a target site identification unit that identifies a site other than the infarct site among the low motion sites, as a target site.
