Recovery of anomaly blood flow contrasts inside the slab-shaped and breast-shaped volume meshes. A sphere anomaly with a diameter of 10 mm and 10-fold flow contrast was placed at 7 mm beneath the surface of background tissue volumes. (a) and (e) show the original assigned anomalies inside the volume meshes with sources and detectors aligned on the mesh surfaces; (b) and (f) show the reconstructed anomalies with full-width at half-maximum (FWHM) thresholds; (c) and (g) show the two-dimensional (2-D) cross-section views of original flow contrast distributions through the anomaly centers; (d) and (h) show the 2-D cross-section views of reconstructed flow contrast distributions.
