Description
Adjusts the scale factor of the Pulsed Repetition
Frequency (PRF).
Shifts the spectral baseline position.
Reverses the spectrum relative to the baseline. When
the spectrum is inverted, Doppler audio is also inverted.
Selects a sixty-degree or zero-degree Doppler angle for
use by the system to calculate velocity.
Identifies the Doppler angle used by the system to
calculate velocity and is an indicator to aid in obtaining
an optimal Doppler angle. Adjusts the Doppler angle in
degree increments.
Activates TEQ ultrasound technology for Doppler.
Changes the transmit frequency of an active
multi-frequency transducer during Doppler.
Rejects low frequency signals, for example, signals
generally caused by tissue clutter.
Adjusts the size of the Doppler gate.
Adjusts the horizontal speed of the Doppler spectrum.
Reverses the Doppler angle, gate axis, and Doppler
spectrum.
Note: Applies to linear array transducers only.
Controls the overall contrast resolution of the image.
Selects a processing curve that assigns echo
amplitudes to gray levels.
Changes the color of the Doppler spectrum by adding
blue, red, yellow, or green to the gray in a gray map.
Adjusts Time/Frequency resolution.
