Abstract: A medical image processing apparatus of an embodiment includes a processing circuitry. The processing circuitry extracts a plurality of valve leaflets of a heart valve from image data of a subject. The processing circuitry measures, with respect to at least one valve leaflet of the valve leaflets, a length of a region at which the valve leaflet is in contact with another valve leaflet, in a predetermined reference direction. The processing circuitry controls a display to display a distribution of the length at each of a plurality of positions on the valve leaflet.

Abstract: An image processing apparatus according to an embodiment includes a processor. The processor acquires medical image data. The processor estimates the structure of a target organ depicted in the medical image data. The processor determines, for each region of the target organ, the degree of certainty representing the accuracy of the estimation result of the structure of the target organ depicted in the medical image data. The processor causes at least information indicating whether user's editing based on the degree of certainty is necessary or information representing a region where user's editing is restricted to be displayed on a display image based on the medical image data.
