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.
