Abstract
According to one embodiment, an ultrasonic image processing apparatus includes processing circuitry. The processing circuitry is configured to acquire volume data based on ultrasonic signals collected by 3D color doppler mode, wherein each voxel value of the volume data includes at least a value of velocity of fluid and a value of power representing intensity of echo signals of the fluid. The processing circuitry is configured to generate a velocity rendering image by volume rendering the volume data using an opacity map in which a relationship between the opacity of the voxel and both the velocity and the power is defined.
