PRF
The Pulse Repetition Frequency (
PRF
) has direct influence on the velocity range.
The higher the Pulse Repetition Frequency the lower the velocity range. As the
display scale increases, the maximum Doppler shift information that can be
displayed without aliasing also increases. Aliasing is where the blood velocity
exceeds the maximum measurable velocity, causing the displayed flow within the
vessel to portray flow in the wrong direction. The disadvantage of using a higher
PRF is a loss of sensitivity to low flow velocities.

Quality Curve
On/Off switch to show or hide the Quality Curve.
Persistence(Persist)
Allows elimination of image speckle from 2D images.
Line Dens.
Line Density optimizes B-Mode frame rate or spatial resolution for the best possible
image. It allows to make a trade-off between image resolution and frame rate.
