Circumference and area (Spline trace)
measurement
To trace the circumference of a portion of the anatomy
and calculate its area:
1. Press Measure twice; a trace caliper displays.
2. To position the first caliper at the start point, move
the Trackball.
3. To fix the trace start point, press Set. The first caliper
becomes yellow and 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.
4. 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.
st
To position the 1 caliper at the start point, move the
Trackball.
5. 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.
Press Set twice to finish this 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.
NOTE: Spline trace is not available through the factory
default. The system defaults to trace.

Echo Level measurement
To make an echo level measurement;
1. Press Measure three times to enable the echo level
measurement. A trace caliper displays.
2. To position the trace caliper at the start point, move
the Trackball.
3. To fix the trace start point, press Set. The trace
caliper changes to an active caliper.
4. To trace the measurement area, move the Trackball
around the anatomy. A dotted line shows the traced
area.
5. To complete the measurement, press Set. The
system displays the echo level in the Results
Window.
NOTE: The echo level measurement is only available
on a frozen image, not on a B-paused image.
