Example optical and x-ray images acquired from a normal breast, showing (a) diffuse transmittance image using full-white illumination acquired by the camera, (b) a tetrahedral breast mesh co-registered with the camera image, (c) separately acquired mammogram of the same breast, with co-registered breast contours extracted from the breast mesh (magenta) and mammogram (green), and (d) compositional prior of the fibroglandular tissue (as volume fraction) derived from the mammogram. The breast contour registration is performed using an iterative closest-point (ICP) algorithm by matching the solid-line portions from both the x-ray and mesh derived contours.
