Pannoramic SCAN 150 1.15 User’s Guide
4 Software Description
Use threshold
•
Scan specimen with auto threshold –
This automatically detects the specimen in the
preview image.
•
Scan specimen with user set threshold –
This sets the sensitivity of the specimen detection.
To set the desired threshold value manually, change the setting in the
Specimen threshold
level
selection box in the range of 0-255. The default value is 35. Smaller values result in a
more sensitive scanning, meaning that more areas will be digitized, however, this may also
include specks or other imperfections of the slide. Greater values result in a less sensitive
scanning, but it is possible that some of the smaller specimen areas will not be digitized.
•
Scan area inside the marker –
If the specimen cannot be identified as required for
digitization, (for example, weak contrast), it can help to encircle completely the specimen
with a black marker pen. You have to draw a full circle with the pen to enable the detection.
Marker pen detection will make specimen detection easier by limiting the scanned area.
If this option is selected, only the area encircled with a marker pen will be scanned. You can
define the threshold level by changing the threshold value in the
Marker threshold level
selection box in the range of 0-255.
This sets the sensitivity of the specimen detection inside the marker area. To set the desired
threshold value manually, change the setting in the
Specimen threshold level
selection box
in the range of 0-255. The default value is 35.
To scan everything within the marked area, check the
Scan everything within marked area
selection box.
Note
:
This step is recommended when using FL mode, as the application is less capable
of finding the specimen based on the specimen threshold level.
