摘要：
A method for converting digital images of an actuated breast into an accurate description of breast surface motion from a digital image-based elasto-tomography system comprises the steps of artificially placing a high density of fiducial markers on the breast surface, whereby the fiducial markers have different qualities and are placed in different proportions according to their quality utilizing motion invariant properties of the fiducial markers to form a global motion invariant signature tracking the markers on the actuated breast surface from image to image in each digital camera using the global motion invariant signature and using the cameras calibration to measure the breast surface motion.
