6 Image Acquisition
Operator’s Manual 6 - 5
Image Quality
Refers to the transmitting frequency in Doppler mode of the probe, the real-time value of which is
displayed in the image parameter area.
B/C Align
To set and constrain the maximum width of the B mode image to that of the Color ROI.
Dual Live
This function is used to display B image and Color image synchronously.
Steer
The feature is used to adjust the ROI of color flow with different angles with immobility of the
probe.
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.
TIP:
Steer is available only for linear probes.
Line Density
The function determines the quality and information of the image.
The higher the line density is, the higher the resolution becomes.
Packet Size
This function is an indication of the ability to detect flow, which is used to adjust the accuracy of
color flow.
The higher the sensitivity is, the more sensitive indication for low-velocity flow becomes.
Flow State
Refers to optimizing the various flow states.
Persistence
This function is to adjust the temporal smooth to optimize the image.
Smooth
This feature is used to reject the noise and smooth the image.
Scale
This function is used to adjust the speed range of color flow, which is adjusted through PRF in the
system. The real-time PRF value is displayed in the image parameter area.
Aliasing may occur if low velocity scale is used and high velocities are encountered.
Low velocities may not be identified when a high velocity scale is used.
Baseline
Refers to the area where the velocity is zero in the scale. Adjust according to the actual situation so
as to get an optimum flow display.
Invert
To set the display mode of the color flow, the color scale will be inverted when the function is
activated.
