Color Mode – Color Flow Mapping 143
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 Color 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
You can invert the way color is assigned to flow information so that flow towards the
transducer appears blue and flow away from the transducer appears red.
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 in the Color mode image inverts.
The 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 Color mode image.
To select the color scale in Color mode:
•
Click the color bar to the right of the image and select the color scale you want.
The color bar to the right of the image is replaced by the one you select.
NOTE: When you scan in Color mode, you cannot use the color bar to change
the B-mode gray scale because it is used to control the Color mode color
mapping.
Multibeam
Multibeam is a method for increasing the frame rate by receiving signals from
several directions (at the expense of resolution).
Multibeam is not available when Auto is turned on.
To select the multibeam level:
•
Click Multibeam under Color, More on the left side of the screen and select
the value you want (or point at Multibeam and press
[
+/-
]
).
