  • Patent number: 7803112
    Abstract: An apparatus for displaying sectional planes of a target object utilizing 3 dimensional (3D) ultrasound data. The apparatus is capable of scanning the target object in real time by improving a scan conversion speed and virtually scans the target object by storing previously acquired 3D data. The apparatus, which displays a target object by using 3D ultrasound data, includes 1) a scan conversion unit for performing scan conversion to convert Cartesian coordinates for display on a screen of a display device to conical coordinates of 3D data, and 2) a rendering unit for rendering multiple sectional plane images, based on the 3D scan conversion, parallel with a reference sectional plane.

  • Patent number: 7628755
    Abstract: The present invention relates to an apparatus for processing an ultrasound image of a target object including a periodically moving object, including: an ROI setting unit for setting regions of interest (ROIs) to each of frames constituting ultrasound volume data acquired from a target object; a VOI setting unit for selecting a predetermined number of first reference frames from the ultrasound volume data and setting a predetermined number of volumes of interest (VOIs) by combining ROIs of the first reference frames with ROIs of frames adjacent to the reference frames; a motion compensating unit for processing the VOIs to compensate a motion of the target object; a correlation coefficient curve calculating unit for calculating a correlation coefficient curve for a predetermined interval at each VOI; a period setting unit for setting a moving period of the moving object based on the correlation coefficient curve in the volume data; and an ultrasound volume data reconstructing unit for reconstructing the ultras

  • Publication number: 20080051653
    Abstract: Embodiments of the present invention may provide an image processing system and method for calculating the volume of a specific portion in a targeted body. According to an embodiment of the present invention, an image processing system may comprise a volume data receiver, a user interface, a display and a main processor. The volume data receiver may form volume data of a target object based on image data thereof. The user interface may receive reference section information on a reference section of the target object, slice section information on a plurality of slice sections each being perpendicular to the reference section and contour information from a user. The display may form an image of the reference section and images of the slice sections based on the volume data. The main processor may set a reference sectional object and slice sectional objects based on the reference section information and the slice section information, respectively.

  • Publication number: 20040213445
    Abstract: An object separating method separates a target object from an ultrasound image. Specifically, first of all, a set of two dimensional (2D) ultrasound images are combined to provide volume data. Then, a rotational axis to rotate the volume data and two points as reference points are set, wherein the two points are points where the rotational axis and the target object intersect. Thereafter, the volume data is rotated by a predetermined angle around the rotational axis to generate a 2D ultrasound image for each rotated angle, wherein the rotating process is repeatedly performed until the volume data is rotated by a preset angle. A contour of each 2D ultrasound image is extracted and vertices on the contour are set to thereby provide contours with vertices. The vertices of each of the contours are wired and processed to provide a 3D image of the target object.
