20090069684 | ULTRASONIC IMAGING APPARATUS AND A METHOD FOR GENERATING AN ULTRASONIC IMAGE - An imaging part transmits ultrasonic waves to a subject and receives reflected waves from the subject, thereby acquiring plural volume data of the subject. A specifying part specifies a surface site included in a face corresponding to the surface of the subject, in each of the plural volume data. A synthesizer executes position matching of the subject shown in each of the plural volume data. The synthesizer couples the plural volume data after position matching, and couples the respective surface sites specified in the respective volume data, thereby generating synthesized volume data. Based on the synthesized volume data, an image generator generates morphology image data showing the morphology of the subject and surface image data showing the coupled surface sites. A display controller controls a display to display a morphology image based on the morphology image data and a surface image based on the surface image data. | 03-12-2009 |
