Image Optimization 5-21
Quick Angle
Description To adjust the angle faster in increments of 60°, and the real-time value of
which is displayed on the right part of the spectrum map.
Operation Adjust through the [Quick Angle] item in the soft menu.
There are 3 angles for quickly adjustment: -60°, 0°, and 60°.
Impacts The function is available in real-time imaging, freeze or cine review status.
Dynamic Range
Description The dynamic range conveys the information being transformed from echo
intensity to gray scale.
Operation Adjust through the [Dyn Ra.] item in the soft menu.
The adjusting range is 24-72dB in increments of 2dB.
Effects The more the dynamic range, the more specific the information, and the
lower the contrast with more noise.
Impacts The function is available in real-time imaging, freeze or cine review status.
Audio
Description This function is used to adjust the output audio in spectrum map,
Operation Adjust through the [Quick Angle] item in the soft menu.
The adjusting range is 0-100%.
Effects Audio helps to identify the feature and status of flow.
Impacts The function is available in real-time imaging, freeze or cine review status.
PW Steer
Description This function is used to adjust the scan angle of linear probes, so as to
change the angle between the transmitting beam and flow direction.
Operation Adjust through the [PW Steer] item in the soft menu.
Values of steering angles vary by probes.
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.
SV
Description To adjust the SV position and size of sampling in PW mode, the real-time
value of SV and SVD are displayed in the image parameter area in the
upper left corner of the screen.
Operation Adjust the SV size through the [SV] item in the soft menu.
Roll the trackball to adjust the SV depth.
Or adjust the SV directly in the image parameter area.
The adjusting range is 0.5-20.0mm.
Effects The smaller the SV size, the more accurate the result; and more
information can be obtained when selected large SV size.
