A medical image capturing apparatus according to an embodiment includes image generation circuitry, detection circuitry, diagnosis support processing circuitry, setting circuitry, and imaging control circuitry. The image generation circuitry generates image data of a subject. The detection circuitry detects each of a plurality of parts of the subject in the image data generated as a positioning image. The diagnosis support processing circuitry executes diagnosis support processing corresponding to a predetermined part with regard to a region corresponding to the predetermined part of the subject detected. The setting circuitry sets an imaging condition of main imaging with respect to a part in which a lesion site is specified as a processing result of the diagnosis support processing. The imaging control circuitry controls an imaging mechanism to perform imaging with regard to an imaging region including the part in which the lesion site is specified based on the imaging condition.
