Velocity, Time Interval and Acceleration
To measure two velocity values, the time interval (ms), and 
acceleration (m/s2):
1. Press Measure three times; an active caliper with vertical 
and horizontal dotted lines displays.
2.  To position the caliper at the start point, 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 at the end point, move the 
Trackball.
5.  To complete the measurement, press Set. The system 
displays the two peak end point velocities, the time interval, 
and the acceleration in the Results Window.
Time interval
To measure a horizontal time interval: 
1. Press Measure four times; an active caliper with a vertical 
dotted line displays.
2.  To position the active caliper at the start point, 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 at the end point, move the 
Trackball.
5.  To complete the measurement, press Set. The system 
displays the time interval between the two calipers in the 
Results Window.

M-Mode Measurements
Basic measurements that can be taken in the M-Mode portion of 
the display are:
• Tissue Depth (Distance)
• Time Interval
•  Time Interval and Velocity
NOTE:  The following instructions assume that you do the following:
1.  In the B-Mode part of the display, scan the anatomy you 
want to measure.
2.  Go to the M-Mode part of the display.
3. Press Freeze.
Tissue depth
Tissue depth measurement in M-Mode functions the same as 
distance measurement in B-Mode. It measures the vertical 
distance between calipers.
1.  Press Measure once; an active caliper with a vertical and 
horizontal dotted line displays.
2.  To position the active caliper at the most anterior point you 
want to measure, 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 at the most posterior point 
you want to measure, move the Trackball.
5.  To complete the measurement, press Set.
The system displays the vertical distance between the two 
points in the Results Window.

To measure time and velocity between two points: 
1.  Press Measure three times; an active caliper with a vertical 
and horizontal dotted line displays.
2.  To position the active caliper at the start point, 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 at the end point, move the 
Trackball.
5.  To complete the measurement, press Set.
The system displays time(s) and slope between the two 
points in the Results Window.
