ULTRASOUND IMAGING SYSTEM FOR EXTRACTING VOLUME OF OBJECT FROM ULTRASOUND IMAGE AND METHOD FOR THE SAME

摘要

The present invention provides an ultrasound imaging system for forming 3D volume data of a target object, including a three-dimensional (3D) image providing unit for providing a 3D ultrasound image; a pre-processing unit for forming a number of two-dimensional (2D) images from the 3D ultrasound image and normalizing the 2D images to form normalized 2D images; an edge extraction unit for forming wavelet-transformed images of the normalized 2D images at a number of scales, the edge extraction unit further being configured to form edge images by averaging the wavelet-transformed images at a number of scales and threshold the edge images; a control point determining unit for determining control points by using a support vector machine (SVM) based on the normalized 2D images, the wavelet-transformed images and the thresholded edge images; and a rendering unit for forming 3D volume data of the target object by 3D rendering based on the control points.
