NOTE:
Heart rate and time measurement methods are the same as those in the M mode.
Reference Section 6.5.2 Generic Measurements in M Mode.
To measure velocity of a point on the Doppler wave:
1. Press Caliper to activate a measurement cursor “+”.
2. Roll the trackball to highlight Velocity and press Set and a “+” is displayed.
3. Roll the trackball and press Set to anchor the point, measuring velocity.
4. Roll the trackball and press Set to begin a new velocity measurement. You
can measure a maximum of eight groups of data. The outcome will be
displayed in the measurement result window, as shown below.
5. Press Caliper to finish and exit.
To measure velocities of two points on the Doppler wave, and calculate the
acceleration:
Acceleration = (Vel1－Vel2) / Interval
1. Press Caliper to activate a measurement cursor “+”.
2. Roll the trackball to highlight Acceleration and press Set and a “+” is
displayed.
3. Roll the trackball and press Set to anchor the first point, measuring Vel1.
4. Roll the trackball and press Set to anchor the second point, measuring Vel2
and Interval, and calculating Acceleration.
5. Roll the trackball and press Set to begin a new acceleration measurement.
You can measure a maximum of eight groups of data. The outcome will be
displayed in the measurement result window, as shown below.
6. Press Caliper to finish and exit.
To measure velocities of two peak points on the Doppler wave, and calculate RI
and S/D:
RI =︱PS－ED︱/︱PS︱
PS: Peak systolic velocity
ED: End diastolic velocity
1. Press Caliper to activate a measurement cursor “+”.
2. Roll the trackball to highlight RI and press Set and a “+” is displayed.
