Frequency
Frequency determines the transmit frequency used by color Doppler.
Upward presses increase the frequency. Downward presses
decrease the frequency.
Steer
This control is only available for linear transducers. It steers the
Color ROI box angle left or right.
Image
Type
Color Doppler supports image presets for Low Flow, Medium Flow,
and High Flow.
Dual Live
To activate split screen with simultaneous live B/Color and live B.
The live B image without color and the same live B image with color
are simultaneously displayed on each side of the image field.
Freezing the image will freeze both sides simultaneously.
Cine review will review both sides simultaneously.
Dynamic
Range
The Dynamic Range, or log compression, adjusts how echo
intensities are converted to brightness. A high dynamic range
presents a flatter, less contrasty color display, while a low dynamic
range presents a more contrasty color display. Only available in
PDI/DPDI mode.
Line
Density
Adjusts the line density to optimize the lateral resolution for the best
possible image. The higher the line density, the higher the lateral
resolution, but the lower the frame rate.
Acoustic
power
Adjusts the acoustic output power of the activated transducer. It is
only available in live imaging. Higher acoustic power numbers
correspond to increased color sensitivity and penetration, but the
ALARA principle should be followed in actual clinical situations.
