A medical image diagnosis apparatus according to an embodiment includes setting circuitry and image generating circuitry. The setting circuitry is configured to obtain position information with respect to a landmark of a patient in a first image generated by performing a first scan on the patient and to set a scan range to be used during a second scan by using the obtained position information, the position information being determined on a basis of the first image and expressed in an image taking system used during the first scan. The image generating circuitry is configured to generate a second image by performing the second scan on the scan range.
