1. An ultrasonic diagnosis apparatus, comprising:
processing circuitry configured to:
generate three-dimensional data based on an echo reflection intensity acquired through a probe;
acquire a plurality of parameters including base color parameters, and the three-dimensional data; and
generate 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, wherein
the processing circuitry is further configured to generate a color attenuation curve based on the base color parameters and an opacity curve defined by associating the echo reflection intensity and an opacity value, and the value of color attenuation is calculated based on the echo reflection intensity, the opacity curve, and the color attenuation curve.
