Segmentations of the choroid slabs were significantly more accurate after attenuation correction. (A-C) Choroid thickness maps of manual segmentation on B-scans after attenuation correction (A), automatic segmentation on regular OCT B-scans (B), and automatic segmentation of attenuation corrected OCT B-scans (C). (D-F) Corresponding B-scans (indicated by the black line on thickness maps) with manual segmentation (white line), and automatic segmentation before (red line) and after (blue line) attenuation correction. (Scale bar: 0.5 X 0.5 mm).
