  • Publication number: 20210219940
    Abstract: An ultrasonic diagnostic apparatus according to an embodiment includes processing circuitry. The processing circuitry is configured to acquire a function index value of each heart chamber for two heart chambers, including the left ventricle, included in a moving image of a heart. The processing circuitry is further configured to generate an image by superimposing a range suggestion image on a two-dimensional coordinate space. In the two-dimensional coordinate space, the processing circuitry allocates the function index value of the each heart chamber to each display dimension corresponding to the each heart chamber and defines the functional index value of the left ventricle as an output coordinate. In the range suggestion image, the processing circuitry colors the range suggestion image according to predetermined normal range and abnormal range for the functional index value of the left ventricle.
