A region-of-interest setting unit sets a region of interest to be included in an ultrasound image. A first movement-amount calculating unit sequentially calculates a movement amount of the set region of interest between reception data along the time sequence as a first movement amount. A transmitting-receiving delay-amount computing unit computes a delay amount for sequentially shifting a scan region of an ultrasonic beam based on the sequentially calculated first movement amount. A computation/control circuit performs control so as to generate a high voltage pulse based on the computed delay amount. A second movement-amount calculating unit sequentially calculates a movement amount of the region of interest between image data along the time sequence as a second movement amount. A display-position correcting unit performs a correction such that the region of interest included in the image data is to be displayed at the same display position, based on the second movement amount.

When an image creating unit creates a three-dimensional ultrasound image of a blood-vessel early phase, an operator presses an image selecting button, and selects an area to be displayed as superimposed by using an image-selecting Graphical User Interface (GUI) displayed by an image-selecting GUI display-control unit. After the image creating unit start creation of a three-dimensional ultrasound image in a late phase, when the operator presses a composition display button, the movement-distance calculating unit calculates a movement distance between a three-dimensional tissue image at the moment of the press of the composition display button and each of three-dimensional tissue images in the area to be displayed as superimposed, and an image correcting unit corrects each of three-dimensional contrast enhanced images corresponding the three-dimensional tissue images of the blood-vessel early phase by using the movement distance. An animated-image compositing unit creates a group of images for animation that the corrected three-dimensional contrast enhanced images of the blood-vessel early phase are each combined with a three-dimensional contrast enhanced image of the late phase, and a monitor displays the group of the images for animation in animation.

In ultrasound diagnosis, a contrast echo technique on three-dimensional scanning is used with a contrast agent injected into an object. Before injecting the contrast agent and under the injection thereof, a blood vessel is continuously and securely targeted and depicted in displayed images. To realize this, a diagnostic ultrasound apparatus has means for acquiring an echo signal by scanning a three-dimensional region of an object with an ultrasound beam, means for producing three-dimensional image data based on the echo signal, means for displaying the three-dimensional image data, means for specifying, for example, from the echo signal, a timing at which injecting an ultrasound contrast agent into a region to be scanned of the object is started, and means for switching over at the specified timing display states of the three-dimensional image data to be displayed by the displaying means. By way of example, the switchovers are carried out such that data produced by projecting the three-dimensional image data on a minimum intensity projection technique are displayed before injecting the contrast agent, while data produced by projecting them on a maximum intensity projection technique are displayed after the start of injecting the contrast agent.
