Accordion to one embodiment, an ultrasound diagnosis apparatus includes a volume data generating unit, an image generating unit, an MPR image generating unit, and a display controller. The volume data generating unit generates, based on position angle information of an ultrasound probe and echo data from the ultrasound probe, functional volume data of a subject accompanied with the position angle information. The image generating unit sequentially generates a sectional image of the subject based on the position angle information and the echo data. The MPR image generating unit generates an MPR image corresponding to the cross-section of the sectional image from the functional volume data based on the position angle information corresponding to the sectional image and the position angle information attached to the functional volume data. The display controller displays the sectional image and the MPR image in parallel or in a superimposed manner on a display.
