1. An apparatus for forming a 3-dimensional (3D) ultrasound image, comprising:
- a generation unit configured to generate a binarization image of a 2D ultrasound image to generate a surface curved line of a target object on the 2D ultrasound image and automatically generate a region of interest (ROI) box for the target object on the 2D ultrasound image by moving bounds of the ROI box to pixels closest to the surface curved line;
a first determination unit configured to calculate a mean square error value between a predetermined standard histogram for a 2D ultrasound image of the target object and a histogram for a 2D ultrasound image within the ROI box, and determine whether the ROI box is suitably generated for a display of the target object therewithin based on the calculation result;
a detection unit configured to detect a contour of the target object in the ROI box; and
a formation unit configured to form the 3D ultrasound image by rendering volume data existing in the detected contour.

Abstract
The present invention relates to a 3D ultrasound diagnostic forming a 3D ultrasound image only with volume data exiting within contour by automatically detecting the contour of a target object, comprising: a first unit for generating a region of interest (ROI) box on a 2D ultrasound image; a second unit for detecting a contour of a target object in the ROI box; and a third unit for forming a 3D ultrasound image by rendering volume data existing in the detected contour.

7. A method for forming a 3-dimensional (3D) ultrasound image, comprising:
-
a) generating a binarization image of a 2D ultrasound image to generate a surface curved line of a target object on the 2D ultrasound image and automatically generating a region of interest (ROI) box for the target object on the 2D ultrasound image by moving bounds of the ROI box to pixels closest to the surface curved line; b) calculating a mean square error value of a predetermined standard histogram for a 2D ultrasound image of the target object and a histogram for a 2D ultrasound image within the ROI box, and determining whether the ROI box is suitably generated for a display of the target object therewith based on the calculation result; c) detecting a contour of the target object in the ROI box; and d) forming the 3D ultrasound image by rendering volume data existing in the detected contour. - View Dependent Claims (8, 9, 10, 11, 12)
