The use of multiple camera angles in mammography gives more information to the radiologist, and thus should reduce the rates of false positives and negatives. Using ideas from computer stereo vision, the authors place multiple views into a 3D reconstruction, and show the 3D position of a lesion occurring in the separate views.

The problem addressed is that the views each show a different deformation of the breast tissue. By using a simplified model of the deformations, the epipolar lines (corresponding to a point in another view) become complex curves in the 3D reconstruction. The intersection of the epipolar curves is the 3D location of the lesion. Results are presented, and future work is suggested. Fourteen references are given.
