Line Density
Description Line density determines the quality and information of the image.
Operations Adjust using the [Line Density] item or the mapping-menu item on the touch screen.
4 levels of line density are provided: H, L, UH, M.
Effects
The higher the line density, the higher the resolution.
Impacts
The higher the line density, the lower 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.
Operations Rotate the knob under the [Packet Size] item or the mapping-menu item on the touch
screen to adjust the value.
There are 3 levels of packet size available: 0 represents no packet size control and the
bigger the value the higher the sensitivity.
Effects
The higher the packet size, the more sensitive the indication for low-velocity flow.
Impacts
Adjusting the packet size may lead to the frame rate changing.
Flow State
Description
This function is used for fast image optimization.
Operations Adjust using the [Flow State] item or the mapping-menu item on the touch screen.
3 levels are provided: L, M, H.
Persistence
Description This function adjusts the temporal smoothing in Color mode to optimize the image.
Operations Adjust through the [Persistence] item or the mapping-menu item on the touch screen.
The system provides 6 levels of persistence adjustment: 0 represents no persistence,
and the bigger the value the stronger the effect.
Smooth
Description
This feature is used to reject noise and smooth the image.
Operations
