Cardiac setup
With CW or PW active, press to adjust these controls. Press again
to return to live imaging.
Baseline Suppress Removes spectral representations of frequencies below
the filter setting.
Frequency Scales Turns the display of frequency scales and frequency
measurements on or off.
Optimum Angle Adjusts the optimum angle-to-flow for linear
transducers (PW only). Most vascular labs use 50 to 60
degrees.
Temporal Smooth Adjusts the amount of horizontal spectral smoothing, to
show envelope outlines according to visual preference.
Units Sets the display of the Doppler velocity scale to cm/s or
m/s (centimeters per second or meters per second).
Changing the display units from cm/s to m/s does not
change the units used for analysis. Analysis
information is always displayed in cm/s.
Velocity Smooth Adjusts the amount of vertical spectral smoothing, to
show the most commonly occurring velocities
according to visual preference.
