Steer Flip
Touch
Steer Flip to flip the PW cursor position round the vertical axis. The steering
angle value changes from plus to minus and vice versa.
PD/HD-Flow
Select PD-Mode or HD-Flow™.
XL-
Changes the monitor from standard mode to wide mode.
Color Off
This function is only available in Read Mode. It turns off color display.
Threshold
This function assigns the gray scale level at which color information stops.
Angle
Image Angle selects a part of interest of the 2D image. The advantage of the
decreased field of view is an increased 2D frame rate due to the smaller sector
width.
Max Angle
Double tap Angle or use on screen gestures to display maximum probe angle.
Quality
The higher the color resolution, the lower the frame rate. Available settings: high,
norm and low.
WMF
The Wall motion filter eliminates vessel wall motion noise that is low in velocity but
high in intensity. Use a wall filter that is high enough to remove motion artifacts, but
that is sensitive enough to display low velocity flows in small vessels. Available
settings: low1, low2, mid1, mid2, high1, high2 and max.
Balance
Balance establishes the amount of color displayed over bright echoes and helps
confine color within the vessel walls. Raising this balance displays color on brighter
structures. If you see color on vessel walls, the balance is probably set too high.
Additionally, wall motion ghosting can be suppressed with a low balance setting.
PRF
The Pulse Repetition Frequency (
PRF) has direct influence on the velocity range.
The higher the Pulse Repetition Frequency the lower the velocity range. As the
display scale increases, the maximum Doppler shift information that can be
displayed without aliasing also increases. Aliasing is where the blood velocity
exceeds the maximum measurable velocity, causing the displayed flow within the
vessel to portray flow in the wrong direction. The disadvantage of using a higher
PRF is a loss of sensitivity to low flow velocities.
Scale
Adjust PRF button to activate Scale. Scale enables the manual adjustment of the
PRF by adjusting the PRF button
Note
Availability depends on probe.
Auto Scale
Auto Scale enables automatic adjustment of the PRF based on color box location
and is activated by the touch monitor.
Note
Availability depends on probe.
