Abstract: According to one embodiment, an ultrasonic diagnosis apparatus includes processing circuitry. The processing circuitry generates three-dimensional data based on an echo reflection intensity acquired through a probe, acquires a plurality of parameters including base color parameters, and the three-dimensional data, and generates a rendering image of the three-dimensional data using a value of color attenuation taking account of propagation of light based on the echo reflection intensity and using the base color parameters.

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.

Abstract: An ultrasonic diagnosis apparatus according to an embodiment includes a processor. The processor acquires Doppler data that is obtained through ultrasonic transmission/reception in a Doppler mode and information about a type of the Doppler mode. The processor determines at least one executable measurement item for the Doppler data based on the information about the type of the Doppler mode.
