Angio Imaging
7-110 Revision D.0
Controls
This section discusses controls for Angio. For information on using Angio with
contrast agents in cardiac presets, see Using Contrast Imaging.
With Angio active, touch PW or CW to go into PW Angio or CW Angio
(combination) mode. The second touch control (PW or CW) is highlighted, and
the Angio control is outlined by a box, indicating that Angio mode is still active.
To exit the combination mode, touch Angio. Now the Angio control is
highlighted, indicating that only Angio mode is active.
Primary
Angio Suppress Removes the color from an image while in Angio
mode. When in combination with PW or CW, the
Angio control is not lit, but is still active and the frame
rate is unaffected.
Angio Compare Compares an angio image with a grayscale version of
the same image. The angio image is displayed on the
right, and the grayscale version on the left.
B/W Suppress Suppresses the black and white image that appears
outside of the color image, thus increasing the frame
rate. Available with sector and curvilinear array
transducers.
Density Trades off resolution versus frame rate by varying line
density.
Filter Removes low-level signals and reduces noise in image.
Focus Repositions the acoustic depth of the angio focal zone.
When Adaptive Angio is on, the focus chooses the
optimal angio frequency.
Frequency Fusion Optimizes frequencies for penetration, texture or
resolution. Changes are reflected in the Frequency
Fusion icon.
