Power
When power is re-
duced, it reduces
the signal-to-noise
ratio, so that the im-
age, spectrum or
color scan may be-
come noisier.
Controls the amount of acoustic power applied in all modes.
When power is set to maximum, it is equal to or less than the
maximum acoustic power permitted by the FDA. The Thermal
Index (TI) and the Mechanical Index (MI) are displayed on the
screen.
Dynamic Range
Enables control of the dynamic range or contrast of the image.
When dynamic range is set to High, the image is softer and
more low-level data is visible.
Contour/Edge Enhance
Controls image processing related to the extent of edge
enhancement applied to an image.
