Meander Scan

Meander Scan is an automated scanning procedure used to ensure that all points within a closed contour are viewed by moving systematically through the contour.

Procedure

  1. Draw a closed contour around the region of interest.

    Use a low-powered lens to draw the contour.

    • If your region of interest has contours within contours, Meander Scan treats the interior contours as an exclusion zone, and does not visit these.
    • If you want to include these areas, select these interior contours, right-click and select Hide Selected Contours.
  2. Click File>Preferences>Movement>AutoMove and Field Movement section.
  3. Set the Field Movement Size to 75% of Screen Size, and click OK.
  4. Click Move>Tools>Meander scan.
  5. In Meander Scan Options, click Start Meander Scan.

    If there is more than one contour, the program displays the Macro View window.

  6. Click inside the desired contour to scan.
  7. Mark, trace, or map anything within the current field of view.
  8. To move to the next scan site, click the icon again and select Next Scan Site or right-click in the tracing window and select Next Scan Site.
  9. If you think you missed something in a previous section, click Previous Scan Site.

 

Use AutoMove if there are structures that extend beyond one field of view.
When using AutoMove, we recommend that you return to the previous site before continuing mapping to ensure that nothing was missed before AutoMove took you away from that scan site.
