A medical image processing apparatus according to an embodiment includes processing circuitry. The processing circuitry acquires the distribution of the wall shear stress of a blood vessel. The processing circuitry extracts a representative value or a blood vessel region from the distribution of the wall shear stress in the blood vessel on the basis of an extraction criterion determined for each region in accordance with the shape or the property of the blood vessel. The processing circuitry changes the display mode of the wall shear stress in the blood vessel on the basis of a result of extracting the representative value of the wall shear stress or a characteristic blood vessel region.

Medical image processing apparatus, system, and method

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.
