1. A diagnostic ultrasound apparatus comprising:

  • signal acquiring means for acquiring an echo signal by scanning a three-dimensional region of an object with an ultrasound beam;

    data producing means for producing three-dimensional image data based on the echo signal;

    displaying means for displaying the three-dimensional image data;

    specifying means for specifying a timing at which injecting an ultrasound contrast agent into the object is started; and

    display switchover means for switching over at the specified timing a display state of the three-dimensional image data displayed by the displaying means, wherein the specifying means is composed of means for automatically specifying the injection timing as the ultrasound contrast agent is injected, the specifying means has setting means for setting the injection timing from the echo signal itself, and the displaying means is means for displaying projection data obtained by projecting two-dimensionally the three-dimensional image data with a desired projection technique and the display switchover means is means for switching over the projection technique at the projection timing specified by the specifying means.
