Sound-speed tomograms for a breast with scattered fibroglandular tissue containing a 27 × 17 × 19 mm invasive ductal carcinoma at 2:00 o'clock. (a) Sound-speed tomograms using bent-ray algorithm (third iteration); (b) Sound-speed tomograms using straight-ray algorithm; (c) Upper panel: sound-speed along the solid line in (a). Sound-speed along the solid line in (a) and the dashed line in (b). The sound-speed scale in (a) and (b) is from 1350 m/s to 1550 m/s.
