Abstract
In an apparatus for ultrasonic diagnosis, an autocorrelation calculator 11 produces Doppler power data P, a shading portion extractor 21 extracts the left-side section of the profile of the ultrasonic image from the Doppler power data P, and a data value converter 22 converts the data value of the extracted shading portion into the data value for shading and converts the data values of remaining portions into a data value different from the data value for shading. The shaded ultrasonic image is visualized as a three-dimensional image so as to facilitate the diagnosis. Particularly, in ultrasonic images of Doppler power mode, blood vessels are visualized as three-dimensional images, and the viewer can identify even small blood vessels accurately.
