Image Optimization 5-17
Operation
Turn on or off the function through the [B Display] item in the soft menu or
menu.
B/C Align
Description
To set and constrain the maximum width of the B mode image to that of the
Color ROI.
Operation
Turn on or off the function through the [B/C Align] item in the soft menu or
menu.
Impacts
Frame rate will increase when the function is turned on.
Dual Live
Description
This function is used to display B image and Color image synchronously.
Operation
Click [Dual Live] in the soft menu or menu to turn on or off the function.
When the function is turned on, the window will be automatically switched
to the dual windows (one for B image, and the other for Color image).
Steer
Description
The feature is used to adjust the ROI of color flow with different angles with
immobility of the linear probe.
Operation
Adjust through the [Steer] item in the soft menu or menu, or rotate the
multifunctional knob to adjust.
Values of steering angles vary by probes.
Effects
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.
Impacts
Steer is available only for linear probes.
Line Density
Description
The function determines the quality and information of the image.
Operation
Adjust through the [Line Density] item in the soft menu or menu.
There are 4 levels of line density provided: UH, H, M, L.
Effects
The higher the line density, the higher the resolution.
Impacts
The higher the line density, the smaller the frame rate.
Packet Size
Description
This function is an indication of the ability to detect flow, which is used to
adjust the accuracy of color flow.
Operation
Adjust through the [Packet Size] item in the soft menu or menu.
There are 4 levels of packet size provided, 0 represents no packet size
control and the bigger the value the higher the sensitivity.
Effects
The higher the packet size, the more sensitive indication for low-velocity
flow.
Impacts
Increasing the packet size will lead to frame rate decrease.
