Abstract: A medical image processing apparatus according to an embodiment includes processing circuitry. The processing circuitry is configured to extract a degree of a disease related to the heart from a medical image; and display, when the degree of the disease related to the heart is high, a first index value related to a blood vessel and calculated from one of blood pressure and a blood flow and configured to display, when the degree of the disease related to the heart is low, wall shear stress serving as a second index value related to the blood vessel, as information related to the blood flow of the blood vessel and calculated on the basis of the medical image.

Abstract: An image information processing apparatus according to an embodiment includes processing circuitry. The processing circuitry acquires a structure from a medical image, sets one or more lines or planes that divide the structure into a plurality of regions, calculates feature quantities related to a form of the structure for each of the regions, and corrects the structure so that a difference in the feature quantities is reduced.

Abstract: A medical image processing apparatus according to an embodiment includes processing circuitry and an input interface. The processing circuitry obtains the spatial distribution of the wall shear stress values at each position of blood vessels. Moreover, the processing circuitry displays, from an arbitrary angle, a display image formed by assigning the wall shear stress values to a three-dimensional image. The input interface receives an input operation for changing the angle. During the display of the display image formed by assigning the wall shear stress values to the three-dimensional image, the processing circuitry changes the display form of the display image between a rotational display in which the display image is displayed while changing the angle with time, and a nonrotational display in which the angle is not changed.
