Image Optimization 5-25
Operations
Rotate the knob under [Baseline] or use the mapping-menu to adjust.
Changes the flow-velocity range to optimize the image.
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 right part of the spectrum map.
Rotate
the <A
ngl
e
/Steer> knob on the control panel to adjust it. 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
right part of the spectrum map.
Adjust using the [Quick Angle] item or the mapping-menu item on the touch screen.
There are 3 angles for quick adjustment: -60°, 0° and 60°.
Dynamic Range
The dynamic range conveys the information which is being transformed from echo
intensity to grayscale.
Adjust using the [Dyn. Ra.] item or the mapping-menu item on the touch screen.
The adjusting range is 24-72dB.
The more the dynamic range, the more specific the information and the lower the
contrast with more noise.
Audio
This function is used to adjust the output audio in the spectrum map.
Rotate the <Volume> knob on the left of the touch panel to adjust the volume.
Press the <Volume> knob to open or shut down the volume.
The adjusting range of the audio is 0-100%.
Utilizing the output audio helps to identify the feature and the status of flow.
PW Steer
This function is used to adjust the angles for the sampling line.
Press the <Angle/Steer> knob on the control panel to switch to “Steer adjustment”.
Rotate the knob to adjust.
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.
The values of steer angles vary according to the probe.
Impacts
The PW Steer function is available only for linear probes.
