Operation Manual

 Doppler Invert

Press the soft menu dial-button [1]. Each time the button is pressed, the speed indicator (+ / –) for

a spectrum is inverted.

 Simultaneous

Press the soft menu’s dial-button [2] to turn the Simultaneous option on or o.

NOTE: This option appears in the PW menu only when Utility > Setup > General > Scan Mode >

Simultaneous Mode is set to Allow.

If the Simultaneous option is turned on, it will be possible to view real-time 2D and spectral Doppler

images at the same time. If the option is not turned on, however, you will only be able to view the

image from one of the modes.

The Simultaneous function decreases Doppler PRF, thus decreasing the measurable speed range.

 Angle

Adjusting the sample volume angle enables accurate speed measurement.

Rotate the soft menu’s dial-button [3] to adjust the angle in 10˚ increments. Pressing the soft menu’s

dial-button [3] changes the angle in the order of –60˚, 0˚, and 60˚.

 SV Size

Used to specify the sample volume size. Rotate the soft menu’s dial-button [4] and set to a value

between 0.5 and 15.

 AutoCalc

Press the soft menu’s dial-button [4] to turn AutoCalc on or o.

If it is turned on, Doppler Trace is performed and its results are displayed. Up to 6 calculations can

be selected under Utility > Setup > AutoCalc. If it is turned on, the Mean Trace button is enabled.

For information on selecting calculations, refer to the ‘Setting Measurements’ section in ‘Chapter 7.

Utilities’.

CAUTION: The measurements done by Auto Trace under Measure and Real Time Automatic

Doppler Trace (Automatic Calculator) may be different from each other. This is because the

algorithms for these two methods are different. It is recommended to use Auto Trace under

Measure for more accurate measurement.
