(Left) Areas of the breast mapped by the LBS. Each small circle represents a single LBS measurement. Complete absorption and reduced scattering spectra were obtained at each spatial location. Measurements were also conducted on the contralateral normal side for comparison. (Right) Trajectory of the biopsy needle in a medial-lateral view. Notice that the needle direction lies under the LBS measurement area. Thus, the direction of the biopsy was not orthogonal to the mapped breast surface.

The point of highest attenuation was assumed to be the best representation of the lesion and was chosen as the center of the LBS scan area (Fig. 1(a)). An incision was made at the surface of the breast at a site away from the lesion [Fig. 1(a)]. Figure 1(b) depicts the orientation of the biopsy needle in relationship to the lesion location and the DOS scan in a medial-lateral view.

An ultrasound of the lesion was performed in order to determine the position, orientation depth, and size (Fig. 2).
