Angle
Description This function is used to adjust the angle between Doppler vector and flow to
make the velocity more accurate.
The real-time adjusting angle value is displayed on the left part of the spectrum
map.
Operations Adjust through [Angle] on the menu.
Tap [-] or [+] to change the value slightly or drag the control directly.
The adjustable angle range is -89~89°, in increments of 1°.
Quick Angle
Description To adjust the angle faster, in increments of 60°. The real-time value is displayed
on the left part of the spectrum map.
Operations Tap the three buttons above [Quick Angle] on the bottom of the image area.
There are 3 angles for quick adjustment: -60°, 0° and 60°.
Dynamic Range
Description The dynamic range conveys the information which is being transformed from
echo intensity to grayscale.
Operations Adjust dynamic range through [Dyn Ra.].
Tap [-] or [+] to change the value slightly or drag the control directly.
The adjusting range is 24-72.
Effects The more the dynamic range, the more specific the information and the lower the
contrast with more noise.
PW Volume
Description This function is used to adjust the output audio in the spectrum map.
Operations Adjust through [Volume] on the menu.
Tap [-] or [+] to change the value slightly or drag the control directly.
The adjusting range of the audio is 0-100%.
Effects Utilizing the output audio helps to identify the feature and the status of flow.
PW Steer
Description This function is used to adjust the angles for the sampling line.
Operations Steer the probe by tapping buttons on the bottom of the image area.
Effects This feature is used to steer the direction of the beam so as to change the angle
between the beam and flow direction with immobility of the linear probe.
Impacts The PW Steer function is available only for linear probes.
