Figure 7 : A-B-scan at slice 85. Yellow line shows depth of horizontal plane in panel B. B-horizontal plane. C-thresholded image before application of size and edge exclusion criteria. D-resultant identified B-line cross-sections with identifying numbers for parameter retrieval.

Oval shapes of B-lines (panel B) were approximated to an ellipse with the major and the minor axes. The mean diameter of fifty two B-lines (panel D) in slice 85 was 0.54 ± 0.2 mm (major axis) and 0.25 ± 0.08 mm (minor axis).
