Title: Ultrasonic image processing apparatus for constructing three-dimensional image using volume-rendering data and surface-rendering data simultaneously

Abstract: An ultrasonic image processing apparatus includes an ultrasonic image input unit, an oblique image rendering unit, a surface extracting unit, a three-dimensional image rendering unit, an image synthesizing unit, and a monitor. The ultrasonic image input unit inputs ultrasonic image data from an ultrasonic probe that is inserted into a body cavity for transmitting or receiving ultrasonic waves. The oblique image rendering unit produces an oblique image. The surface extracting unit extracts surface data from the oblique image (boundary between a tissue and lumen). The three-dimensional image rendering unit produces three-dimensional images using volume-rendering data and surface-rendering data respectively. The image synthesizing unit reads the three-dimensional images produced by the three-dimensional image rendering unit and synthesizes the three-dimensional image of volume-rendering data and the three-dimensional image of surface-rendering data. The monitor displays a three-dimensional image produced by the image synthesizing unit.
