Operation Manual

Color/Power Doppler Mode

X

A protocol is not specied 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 ow 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.

Measurement Accuracy Table

The following tables show the accuracy of the measurements available using the product. Ensure that

the results of measurement accuracy checks are kept within the ranges specied in the table. Except for

certain applications or probes, the following accuracy ranges should be maintained for measurement of

a straight distance.

NOTE: To ensure accurate measurements, an accuracy check should be performed at least

once per year. If the measurement accuracy falls outside the ranges speciﬁed in the following

table, contact Samsung Medison Customer Service.
