Circumference and area (spline trace) measurement
To trace the circumference of a portion of the anatomy and
calculate its area:
1. Press Measure key to enter into measure mode, if
necessary.
2. Adjust Caliper Change in the Primary Menu to Spline.
NOTE: The available values for Caliper Change menu can be set
in Utility -> Measure -> Advanced preset -> Measure Key
Sequence.
3. To position the first caliper at the start point, move the
Trackball.
4. To fix the trace start point, press Set. The first caliper turns
yellow. The second caliper appears at the same position as
the first caliper and is green.
NOTE: When pressing the Clear key once, the second caliper
disappears and the first caliper is activated.
If Clear is pressed again, the first caliper disappears and the
Spline trace is cancelled.
5. To position the second caliper, move the Trackball and
press Set. The third caliper appears at the same position.
NOTE: The Clear key functionality is the same as noted in the
previous step.
The spline trace requires at least three points to draw the
trace. Continue setting the points of the trace until the
desired points are set.
6. Press Set again after the last caliper is fixed to finalize the
spline trace. All points are removed from the line and the
spline trace turns yellow.
NOTE: Pressing Set twice finishes the trace measurement.
If Clear is pressed twice when more than 3 points exist on
the trace, all points are removed and the first caliper again
displays.
