Expected Result(s)
Threshold assigns the gray scale level at
which color information stops.
Controls the number of samples gathered for
a single color flow vector.
Allows a specific color map to be selected.
After a selection has been made, the color
bar displays the resultant map.
Enables the adjustment of the probe's
operating frequency. Press Frequency and
select desired value. The selected frequency
is displayed in the status window.
Averages color frames. Press Frame
Average up/down to smooth temporal
averaging.
Views blood flow from a different perspective.
Press Invert to reverse the color map.
Trades frame rate for sensitivity and spatial
resolution. If the frame rate is too slow,
reduce the size of the region of interest,
select a different line density setting, or
reduce the packet size.
Dynamic Range controls how echo
intensities are converted to shades of gray,
thereby increasing the adjustable range of
contrast.
Eliminates the motion artifacts. Press Ace to
activate.
Slants the Color Flow region of interest or the
Doppler line to obtain a better Doppler angle.
Adjusts the baseline to accommodate faster
or slower blood flows to eliminate aliasing.
Velocity scale determines pulse repetition
frequency. If the sample volume gate range
exceeds single gate PRF capability, the
system automatically switches to high PRF
mode. Multiple gates appear, and HPRF is
indicated on the display.
Allows to select specific transparency map
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.
