4-4-8-5 Checks
•Adjust the Gain to set the gain in the color flow area.
•Adjust Scale to the highest setting that provides adequate flow detection.
NOTE: The scale value may affect Power Output, frame rate, and wall filter.
•Adjust Wall Filter to remove low velocity blood flow and motion artifacts that reduces image quality.
•Adjust Sample volume (SV) to a low setting for better flow resolution, or a higher setting to more
easily locate disturbed flows
•Adjust Frequency to optimize the color flow display. Higher settings improve resolution. Lower
settings improve depth penetration and sensitivity. This does not affect the frequency used for B
and M-Mode.
• • Adjust Acoustic output power to obtain an acceptable image using the lowest setting possible.
NOTE: The Power setting affects all other operating modes.
Adjust the following settings to further optimize display of the image:
•Use Invert to reverse the color assignments in the color flow area of the display.
•Use Threshold to emphasize either the color flow overlay, or the underlying grey scale tissue detail.
•Use Baseline to emphasize flow either toward or away from the probe.
