Operation Manual
Color/Power Doppler Mode
X
A protocol is not specified for images in Color Doppler Mode or Power Doppler Mode. Therefore,
the same limitations imposed on measurements taken in B/W images also apply to the accuracy
of measurements taken in Color Doppler and Power Doppler Modes.
X
Using Color/Power Doppler Mode images for measuring accurate blood flow velocity is not
recommended.
X
The amount of blood flow is calculated based on the average velocity rather than the peak
velocity.
X
In all applications, the amount of blood flow is measured in PW Spectral Doppler Mode.
Cursor Position
X
All measurements are affected by input data.
X
To ensure accurate positioning of the cursor:
Adjust the images on the screen so that they are displayed at maximum granularity.
Use the front edge or boundary point of a probe to make the start and end points of a
measurement object more distinct.
Make sure that the probe direction remains aligned during measurement.
