Abstract: An apparatus and method for segmenting a medical image are provided. The apparatus includes a user interface unit, which provides interface with a user, a volume data input unit, which inputs medical image information; a two-dimensional image display control unit, which receives the volume data, generates and displays a two-dimensional image corresponding to a predetermined position in the medical image, and performs segmentation of the two-dimensional image; and a three-dimensional image display control unit, which receives the volume data, generates and displays a three-dimensional image with respect to the medical image, performs segmentation of the three-dimensional image, transmits the result of the segmentation to the two-dimensional image display control unit, receives position information of the two-dimensional image and the result of the segmentation of the two-dimensional image form the two-dimensional image display control unit, and displaying them on the three-dimensional image.

Abstract: A reference image is displayed by processing spatial distribution to image data recording. A screen for inputting a corresponding command is displayed when requested. A corresponding slab is a three-dimensional slab rendered according to an input of a slab control command on a displayed screen. The three-dimensional rendered slab is also displayed. When the slab control command is designated among the Sagittal image, the Coronal image, and the Axial image on the displayed screen, the image designated on the basis of the reference image is displayed. When the slab control command is designated as a request to Rotate on the displayed screen, it is checked whether a new rotation center is designated. When the new rotation center is designated, volume or interest (VOI) planes are rotated on the basis of the new rotation center and the image is generated and displayed.

Abstract: An apparatus and method for displaying a three-dimensional virtual endoscopic image are provided. In the method, information on a virtual endoscopic image is input in the form of volume data expressed as a function of three-dimensional position. A two-dimensional reference image, a three-dimensional reference image, and a virtual endoscopic image are detected from the volume data. The detected images are displayed on one screen. Virtual cameras are respectively displayed on areas, in which the two and three-dimensional reference images are respectively displayed. Here, a camera display sphere and a camera display circle are defined on the basis of a current position of each virtual camera. When information regarding to one image, among the two and three-dimensional reference images and the virtual endoscopic image on one screen, is changed by a user's operation, information regarding to the other images is changed based on the information changed by the user's operation.
