A nonrigid-body approach to matching mammograms

This paper has explored the use of a nonrigid-body approach to mammogram registration. Mammogram registration is inherently complicated by factors such as the inhomogeneous composition of the breasts and their nonrigid behavior. We have developed a technique which accounts for such nonrigid-body idiosyncrasies and allows corresponding mammograms to be registered for subsequent fusion. Future work in this area involves the development of techniques to extract control-points from the inner portion of the breast and integration into a completely autonomous comparative analysis schema
