NOTE: The following instructions assume that you first scan the patient and then press Freeze .
4-3-10-1 Distance and Tissue Depth Measurements
1.) Press MEASURE once; an active caliper displays.
2.) To position the active caliper at the start point (distance) or the most anterior point (tissue
depth), move the TRACKBALL .
3.) To fix the start point, press Set . The system fixes the first caliper and displays a second active
caliper.
4.) To position the second active caliper at the end point (distance) or the most posterior point
(tissue depth), move the TRACKBALL .
5.) To complete the measurement, press SET . The system displays the distance or tissue depth
value in the measurement results window.
Before you complete a measurement:
To toggle between active calipers, press MEASURE .
To erase the second caliper and the current data measured and start the measurement again, press

but not data entered onto worksheets, press CLEAR.
4-3-10-2 Circumference/Area (Ellipse) Measurement
1.) Press MEASURE once; an active caliper displays.
2.) To position the active caliper, move the TRACKBALL .
3.) To fix the start point, press SET . The system fixes the first caliper and displays a second active
caliper.
