Image Optimization 5-19
Operation
Tap [Tint Map] on the touch screen to complete the adjustment.
There are 8 kinds of maps provided: P0-3 belongs to Power Mode maps, while dP0-3
belongs to Directional Power Mode maps.
The Power maps provide information of blood flow, which are highly sensitive to the
low-velocity flows.
The Directional Power maps provide information of flow direction.
Dynamic Range
Description
This function is to adjust the transformation of echo intensity into color signal.
Operation
Tap [Dynamic Range] on the touch screen to adjust the parameters.
The adjusting range is 10-70 in increments of 5.
Gray Map
Increasing dynamic range will lead to higher sensitivity to low-power signals, thus
enhances the range of signals to display.

V Flow
V Flow shows the blood direction and velocity via the arrow. The arrow length represents the velocity,
and the arrow orientation represents the direction of the blood flow.The blood flow is displayed according
to the updates of the arrow position and the velocity.
V Flow shows the blood situation on vortex flow, turbulent flow, regurgitation, etc.
Description
1. V Flow imaging is an option.
2. Only L11-3U and L9-3Uprobe supports the exam mode of arteria cartois. You can
enter V Flow on B/Color real-time scan mode.
3. It only supports single-window display, but does not support dual-window display and
quad-window display.
4. V Flow image does not support the image magnification.

V Flow Basic Operations
1. Scan the arteria cartois on the real-time B/Color mode; adjust the probe and the image to locate the
desired region at the center of the B/Color mode image.
2. Tap [V Flow] or user-defined key (set the V Flow key via [Preset]
[System]
[Key Config]) to enter
V Flow mode. Roll the trackball to locate the ROI, and press <Set> and roll the trackball to adjust the
ROI position and the size.
