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.

Abstract: A system and a method generate a 3-D image by fast computing the distance between adjacent 2-D images. The method comprises the steps of: producing a first main frame, a second main frame parallel to the first main frame, and a supplementary frame inclined at an angle with respect to the first main frame; creating a virtual frame by using the first main frame and the supplementary frame; calculating a first correlation coefficient between the first main frame and the virtual frame; computing a second correlation coefficient between the first and second main frames; and estimating a distance between the first and second main frames. The system comprises a probe for generating pairs of image frames; a distance calculating unit for calculating distances between main frames of the pairs; and a screen for displaying a 3-D image of the target produced by using the distances.

Abstract: An ultrasonic imaging system for an ultrasonic imaging unit generating ultrasonic image data of an interlaced scanning mode, includes a display of a non-interlaced scanning mode and a scanning mode converter for converting ultrasonic image data of the interlaced scanning mode received from the ultrasonic imaging unit into data of a non-interlaced scanning mode and supplying the ultrasonic image data of the non-interlaced scanning mode to the non-interlaced scanning mode display, to thereby provide an ultrasonic image having a better quality of picture in comparison with the interlaced scanning mode. The only ultrasonic image data in which the ultrasonic image data is displayed together with additional data on a screen by the image display of the non-interlaced scanning mode, is converted in the interlaced mode, thereby recording the ultrasonic image data via the conventional VCR.
