Abstract: An ultrasonic diagnostic apparatus of an embodiment includes processing circuitry. The processing circuitry is configured to acquire a B mode image in which a signal intensity of reflected waves obtained in such a manner that ultrasonic waves are transmitted to a scanning area in a subject and reflected in the subject is represented by luminance levels, and a Doppler image of a region of interest included in the scanning area. The processing circuitry is configured to cause a display to display the Doppler image superposed on the B mode image acquired. In addition, the processing circuitry is configured to change a display mode of the Doppler image displayed on the display using a feature quantity obtained on the basis of at least one of the B mode image and the Doppler image in a time series acquired.

Abstract: According to one embodiment, a medical image diagnostic apparatus includes processing circuitry. The processing circuitry configured to acquire first volume data and second volume data relating to a subject, set a first region of interest for the first volume data, set a second region of interest for the second volume data independently from setting of the first region of interest, perform a cropping process on the first volume data and the second volume data based on information representing the first region of interest and the second region of interest, and generate display image data based on the first volume data and the second volume data that have been subjected to the cropping process.
