6 Image Acquisition
WF (Wall Filter)
To display the image accurately, it adjusts the cut-off used in the wall filter, and filters out the flow
noise which is produced by vessel wall vibration. The real-time value is displayed in the image
parameter area.
Tint Map
This function provides an imaging process based on color difference rather than gray distinction.
Gray Map
Selects among post processing map curves to optimize grayscale images.
Display Format
Sets the display proportion of PW mode image and B mode image.
Duplex/Triplex
This function is used to set if B image or B+Color image (Power) is scanned synchronously.
HPRF
HPRF mode is used when detected velocities exceed the processing capabilities of the currently
selected PW Doppler scale or when the selected anatomical site is too deep for the selective PW
Doppler scale.
Baseline
Refers to the area where the velocity in zero in the spectrum. The map changes after being edited.
Angle
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 in the image parameter area.
Quick Angle
Adjusts the angle faster in increments of 60°, and the real-time value of which is displayed in the
image parameter area.
Dynamic Range
The dynamic range conveys the information that being transformed from echo intensity to gray
scale.
Audio
Adjusts the output audio in spectrum Doppler.
Steer
Adjusts the scan angle in PW mode, so as to change the angle between the transmitting beam and
flow direction.
Obtain more information with immobility of the probe.
Values of steer angles vary with the probe.
TIP:
Steer is available only for linear probes.
