An ultrasonic diagnostic device for forming a 3-D echo data capturing area. A beam address array is comprised of a plurality of ultrasonic beam addresses constituting a 3-D echo data capturing space. The beam address array is divided into a plurality of address groups, for each of which two address scans are executed repeatedly. Accordingly, a time interval between two pieces of data is shortened, when differential operation is performed on two pieces of data acquired in the same beam position. The presence or behavior of ultrasonic contrast media in a biological tissue is displayed as a 3-D differential image. |
