Dynamic Range No Dynamic Range controls how echo intensities are converted to
shades of gray, thereby increasing the adjustable range of contrast.
The Dynamic Range control name changes to Compression on
frozen images.
Reverse (if Preset) No Flips the image 180 degrees left/right.
Line Density Yes Optimizes B-Mode frame rate or spatial resolution for the best
possible image.
Maps No The system supplies B, M, and Doppler Mode system maps.
Frame Average No Temporal filter that averages frames together, thereby using more
pixels to make up one image. This has the effect of presenting a
smoother, softer image.
Colorize No Colorize is the colorization of a conventional B-Mode image or
Doppler Spectrum to enhance the user's ability to discern B, M, and
Doppler Mode intensity valuations. Colorize is NOT a Doppler Mode.
NOTE: You can colorize realtime or CINE images or Timeline CINE,
but not DVR images.
Colorizes the gray scale image to enhance the eye's discrimination
capability. Spectrum Colorize colorizes the spectrum as a function of
power using the inverse of the Colorize map for the signal intensity in
each Doppler line. Colorize enhances the visibility of the spectrum's
characteristics and enhances your ability to identify spectral
broadening and the edge contours of the spectrum used to define
the peak frequency/velocity.
The gray bar displays while Colorize is activated.
Rotation No Flips the image 180 degrees up/down.
CAUTION: When reading a rotated image, be careful to observe the
probe orientation to avoid possible confusion over scan direction or
left/right image reversal.
Rejection No Selects a level below which echoes will not be amplified (an echo
must have a certain minimum amplitude before it will be processed).
Suppression No Suppresses the noise in the image.
Speed of Sound No Changes the transmitted speed of sound for various tissue types.
