Step Task Expected Result(s)
1
Activate Colorize
Enables gray scale image colorization. To
deactivate, reselect a Gray Map.
2
Adjust Edge Enhance
Edge Enhance brings out subtle tissue
differences and boundaries by enhancing the
gray scale differences corresponding to the
edges of structures. Adjustments to M Mode's
edge enhancement affects the M Mode only.
3
Activate Grey Map
Determines how the echo intensity levels
received are presented as shades of gray.
4
Adjust Frequency
Multi Frequency mode lets you downshift to
the probe's next lower frequency or shift up to
a higher frequency.
5
Adjust Frame Average
Temporal filter that averages frames together.
This has the effect of presenting a smoother,
softer image.
6
Adjust Rotation
Rotates the image by selecting the value from
the pop-up menu.
7
Power output
Optimizes image quality and allows user to
reduce beam intensity. 10% increments
between 0-100%. Values greater than 0.1 are
displayed.
8
Dynamic Range
Dynamic Range controls how echo
intensities are converted to shades of gray,
thereby increasing the adjustable range of
contrast.
9
Focus Number and Position
Increases the number of transmit focal zones
or moves the focal zone(s) so that you can
tighten up the beam for a specific area. A
graphic caret corresponding to the focal zone
position(s) appears on the right edge of the
image.
10
Adjust Rejection
Selects a level below which echoes will not be
amplified (an echo must have a certain
minimum amplitude before it will be
processed).
