Description
Adjusts the repetition rate of the Doppler pluses transmit-
ted when acquiring the data for color flow mapping. The
Scale (Nyquist limit) should be adjusted so that no aliasing
occurs, while still having good resolution of velocities. The
Nyquist limit should be somewhat above the maximum
velocity found in the data.
LVR, also called wall motion filter, adjusts the extent of low
velocity removal.
Control the angle of the color sample volume (Only for
Liner Array Probe).
Adjusts the transmission frequency to control the sensitiv-
ity and the level of penetration. The selected frequency is
displayed in the status window. Adjusting Frequency may
affect Sample Volume and LVRej settings.
Switch to Power Mode.
Adjusts the Frame Rate.
Adjusts the color map to emphasize flow either towards or
away from probe. Baseline is available in both Live and
Freeze.
BC SameWidth
Adjusts the
width of 2D Mode is the same as that of Color Mode.
Description
Prioritize colors in the Color mode.
Improve the sensitivity of the signal in time domain.
Smooths the image by averaging collected horizontal line.
Increasing lateral averaging will reduce noise, but may
also reduce lateral resolution.
Smooths the image by averaging collected radial line.
Increasing radial averaging will reduce noise, but may also
reduce radial resolution.
Displays a menu of color map options. Each color map is
assigning different color hues for different velocities.
