Reference Section 6.6.2 Generic Measurements in M Mode.
To measure velocity of a point on the Doppler wave:
1. Press Measure 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 four groups of data. The outcome will be
displayed in the measurement result window, as shown below.
5. Press Measure to finish and exit.
Refer to the heart rate measurement in 6.6.2 Generic Measurement in M mode.
To measure velocities of two points on the Doppler wave, and calculate the
acceleration:
Acceleration = (Vel1－Vel2) / Interval
1. Press Measure 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 four groups of data. The outcome will be
displayed in the measurement result window, as shown below.
6. Press Measure to finish and exit.
To measure velocities of two peak points on the Doppler wave, and calculate RI
and S/D:
RI = (Vel1－Vel2)/Vel1
1. Press Measure to activate a measurement cursor “+”.
2. Roll the trackball to highlight RI and press Set and a “+” is displayed.
3. Roll the trackball and press Set to anchor the first peak point, measuring Vel1.
4. Roll the trackball and press Set to anchor the second peak point, measuring
