Demonstration of the solid prostate phantom. (a) 2D ultrasound image of solid prostate phantom, including the depicted contour. (b) 2D positions of prostate phantom contour, CDFs (red), and detectors (green). The inserts a, b, and c represent anomalies of optical properties for solid prostate phantom. (c) 3D geometry of solid prostate phantom, locations of CDFs (red), detectors (blue) and anomalies (blue solid).
