Image reconstruction with the use of a sound speed model (for the second case study). Note the focusing and contrast enhancement of structures in the resulted image of (a). The sound speed image (b) used for this reconstruction was obtained using the algorithms described in Ref. 12. The sound speed values are represented in km∕s. For cancers in breasts with much lower density, the mass (indicated by the arrow) is very apparent with transmission tomography.
