Abstract
A method for an optical elastography system converts digital images of an actuated breast into a description of surface motion. The surface motion can subsequently be used to ascertain whether the breast has regions of abnormal stiffness, e.g., indicating a significant likelihood of breast cancer. The steps of the method use a model based segmentation to identify profile of the breast in each image, and for each pair of images computing skin surface motion using an optical flow algorithm. This method eliminates a preliminary step of placing fiducial markers on the subject.
