Virtual light delivery system: (a) five linear fiber-optic segments (red lines) are attached on the surface of an arc-shaped illuminator (radius of 145 mm, central angle of 80 deg), and (b) five cone beams (half-angle of 12.5 deg) are emitted from the locations uniformly distributed on each linear fiber-optic segment. Panels (a) and (b) show light delivery at an illumination view. The total number of illuminator arcs is 20, so 500 cone beams illuminate the breast.
