Fig. 12

(a) Section of a B-scan with adjacent stripes of reflection (surrounding left arrow) and shadowing (right arrow) which produce false ROIs. (b) B-scan section from 12a with yellow representing the corresponding ROI map generated for this image. The vertical red stripes represent detected stripes of reflection while the vertical blue stripe represents detected stripes of shadowing. (c) Section of a B-scan with separation between capsule and cortex. The arrow indicates pockets at the point of separation which produce false ROIs. (d) B-scan section from 12c with yellow representing the corresponding ROI map. The arrow indicates a region (red) where separation of the capsule and cortex produces false ROIs.
