Question

What is the difference between overlapped and underlapped scanning?

Answer

When scanning a region of interest, adjacent fields may be...

• Overlapped (fields can be stitched into a contiguous image),
• Tiled (adjacent fields do not overlap enough to stitch but may overlap a few pixels),
• Underlapped (there is a gap between fields with no chance of duplicate tissue from field to field).

The field overlap settings are found under Device Settings—Scan Options—Field Overlap Settings.

The above settings generate the following whole scan images.

Note
When whole scan images are created for underlapped scans, gaps (or gutters) are added between each field (as shown in the above image).
