Verifying the Stage Position/Using the Offset Function

When reviewing FOVs, the stage moves according to the location coordinates recorded in the
database for that slide. Before beginning reviewing, the stage position must be verified.
The first FOV displayed on the slide map is for Location Confirmation. This exclusive Location
Confirmation image presents a unique object to the screener to facilitate easy visualization.
Figure 3-9 illustrates the slide map with the stage focused on the first FOV (Location
Confirmation). Note the 20x magnification black and white image in the primary image area and
the border of the slide map in red. The red border indicates this is the first FOV and is to be used
for Location Confirmation. The image in the primary display should match the view as seen
through the microscope at 10x magnification.
When viewing through the microscope at 10x magnification, the
unique location confirmation image should appear close to the
center if calibration of x and y coordinates was successful.

If the unique object in the primary image field matches what is seen through the oculars,
continue to Section 3.5.
If the image does not match the view or the image is not at the center of the microscopic view
through 10x magnification, do the following:
1
Use the manual stage controls to re-align the object so it matches the image in the primary
display.
2 Select Offset located in the toolbar. The stage will move and adjust to the new offset
position. The offset function allows the user to fine tune FOV positions.
