3D Reconstruction of Solid Breast Nodule in Ultra Sonographic Image

Abstract

Breast cancer is one of the most frequent forms of cancer among women all over the world and the early detection of the cancer provides a better chance of proper treatment. A method for automatically reconstructing a 3-dimensional object (nodule) from serial cross sectional Ultra Sonographic data is presented in this paper. The segmentation of region of interest (ROI) is the most crucial step in 3dimensional nodule construction for which Fuzzy Stopping Force Level Sets equation is employed [11]. The method combines the Dynamic Elastic Contour Interpolation algorithm [22] to generate a series of intermediate missing contours between each pair of consecutive cross sections. These slices are connected in a definite order and rendered using Phong shading for smooth and complete surface of 3D nodule can thus be reconstructed
