A computer-aided three-dimensional display system for ultrasonic diagnosis of a breast tumour.
This paper describes a three-dimensional (3-d) display method by which the shape of an abnormal tissue, say, a breast tumour is represented as a line picture on a cathode ray tube (crt). The 3-d image consists of a set of overlaid contour lines, each of which shows the boundary of the tissue and is obtained from the corresponding B-scan digitized image by using image processing techniques such as smoothing and Laplacian. The system together with the 3-d algorithm is explained and some of the experimental results and pertaining problems are discussed.
