You can use custom presets to choose an inner boundary and an outer boundary, and then
shift them to visualize the vasculature between any of the defined layers.
B-Scan Settings
Based on the selected slab (Current View), allows you to step through the scan by dragging
the segmentation lines, offsetting the outer and/or inner segmentation boundaries, in
μ m.
Images generated using settings on this screen can be recorded using , which will
allow you to save the image(s) in a number of selectable raster formats, in the
location specified.
• B-scan Flow (one color or two color): Selecting this option adds one or two colors to
the B-scan viewport. Selecting
One Color
will show all aspects of the flow in light red.
Choosing
Two Color
will overlay the scan such that the light red will overlay the data
lying above the RPE and green will overlay data lying below the RPE.
• Segmentation Lines: Selecting this option adds the dashed magenta lines to the
segment viewport (lower left).
1.Select Edit.
2.Left-click the mouse at an end (where the triangle is) of one of the lines and
hold down the mouse button to move it. This will change the offset and define a
new slab.
These changes will be reflected in the AngioPlex and Structure images above. You
cannot use segmentation lines when the images are overlaid with a thickness map.
NOTE: This option is not available for Montage Angio.
