5-14 Image Optimization
Steer
Description
The feature is used to adjust the ROI of color flow with different angles with immobility of
the probe.
Operation
Rotate the knob under the <Steer> on the control panel to adjust the steer angle or toggle
<Steer> to adjust the value.
Gray Map
This function is used to adjust the scan angle of the probes, so as to change the angle
between the transmitting beam and flow direction.
Impacts
Only for linear probes.
Line Density
Description
The function determines the quality and information of the image.
Operation
Tap [Line Density] on the touch screen to adjust the parameters.
Levels of line density: UH/H/M/L.
Gray Map
The higher the line density is, the higher the resolution becomes.
Impacts
The higher the line density is, the higher the resolution becomes.
Sensitivity
Description
This function is an indication of the ability to detect flow, which is used to adjust the
accuracy of color flow.
Operation
Rotate the knob under the [Packet Size] item on the touch screen to adjust the value.
There are 3 levels of sensitivity provided, 0 represents no packet size control and the
bigger the value is, the higher the sensitivity becomes.
Gray Map
The higher the sensitivity is, the more sensitive indication for low-velocity flow becomes.
Impacts
It affects the frame.
Flow State
Description
Refers to optimizing the various flow states.
Operation
Tap [Flow State] on the touch screen to adjust the parameters.
Levels: H/M/L.
Persistence
Description
This function is to adjust the temporal smooth to optimize the image.
Operation
Tap [Persistence] on the touch screen to adjust the parameters.
The system provides 6 levels of persistence adjustment; 0 represents no persistence.
The bigger the value is, the stronger the effect becomes.
Smooth
Description
This feature is used to reject the noise and smooth the image.
