4-3-6 Basic Measurements
NOTE: The following instructions assume that you first scan the patient and then press Freeze.
4-3-6-1 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
CLEAR
once.
NOTE: To rotate through and activate previously fixed calipers, turn CURSOR SELECT
.
NOTE: After you complete the measurement, to erase all data that has been measured to this point,
but not data entered onto worksheets, press CLEAR
.
4-3-6-2 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.
4.) To position the second caliper, move the TRACKBALL
.
5.) Turn the ELLIPSE
control; an ellipse with an initial circle shape appears.
NOTE: Be careful not to press the Ellipse control as this activates the Body Pattern.
6.) To position the ellipse and to size the measured axes (move the calipers), move the
TRACKBALL
.
7.) To increase the size, turn the ELLIPSE
control in a clockwise direction. To decrease the size,
turn the ELLIPSE
control in a counterclockwise direction.
8.) To toggle between active calipers, press MEASURE
.
9.) To complete the measurement, press SET
. The system displays the circumference and area
in the measurement results window.
Before you complete a measurement:
- To erase the ellipse and the current data measured, press CLEAR
once. The original caliper
is displayed to restart the measurement.
- To exit the measurement function without completing the measurement, press CLEAR
a
second time.
