Image Optimization 5-15
Steer
The feature is used to adjust the ROI of the color flow of different angles with
immobility of the linear probe.
Steer the probe by tapping buttons on the bottom of the image area.
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.
Steer is only valid for linear probes.
Line Density
Line density determines the quality and information of the image.
Adjust through [Line Density] on the menu.
The higher the line density, the higher the resolution.
The higher the line density, the lower the frame rate.
Packet Size
This function is an indication of the ability to detect flow, which is used to adjust
the accuracy of color flow.
Select different effects through [Packet Size].
0 represents no packet size control and the bigger the value the higher the
sensitivity.
The higher the packet size, the more sensitive the indication for low-velocity flow.
Adjusting the packet size may lead to the frame rate changing.
Flow State
This function is used for fast image optimization.
Select different effects through [Flow State].
Persistence
This function adjusts the temporal smoothing in Color mode to optimize the
image.
Select different effects through [Persistence].
0 represents no persistence, and the bigger the value the stronger the effect.
Smooth
This feature is used to reject noise and smooth the image.
