2D Filter
Sometimes the color information in the image has an uneven appearance. A
smoothing function can help even out the color information. You can set a 2D filter
level to select the amount of color smoothing you want.
To set the 2D filter level:
•
Click 2D Filter under Power on the left side of the screen and select the value
you want (Off, Low, Medium or High).
The current setting is displayed on the screen next to 2D Filter.
Color Priority
When color information is superimposed on a B-mode image, color can appear
outside vessels, making it appear that the flow is not restricted to the vessel. To
minimize this effect, you can adjust the color priority. Make the color priority lower
to have less color outside the vessels.
To adjust the color priority:
•
Click Color Prty under Power on the left side of the screen and drag the slider.
The current setting is displayed on the screen next to Color Prty.
NOTE:
High color priority gives color in more areas; low color priority reduces
the number of areas that are colored.
Invert
In the Power+Velocity submode, as in Color mode, you can invert the way color is
assigned to velocity flow information.
To invert the color coding or to return to the default:
•
Press
[
I
nverse
]
to toggle between the default and inverted color coding.
The color coding of the velocity information inverts.
The velocity color bar to the right of the image is inverted to show the new color
coding.
Color Mapping
Various color scales can be used to display a Power mode image. The color bar is
different in the 2 submodes. In Power + Velocity, the bar is vertical but the intensity
changes in the horizontal direction.
To select the color scale in Power mode:
•
Click the color bar to the right of the image and select the color scale you want.
