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 when measurements are taken in B/W images apply to
the accuracy of the measurements taken in these modes.
X
It is not recommended to use images in Color/Power Doppler Mode for measurement of
accurate blood ow velocity.
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 ow is measured in PW Spectral Doppler Mode.
Cursor Position
X
All measurements are aected 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 is always aligned during measurement.
