HPRF HPRF mode is used when detected velocities exceed the processing capabilities of
the currently selected PW Doppler scale or when the selected anatomical site is too
deep for the selected PW Doppler scale.
Time Scale Each selection represents a different sweep time.
Angle Correct Indicates flow direction.
Sample Volume
Gate
Indicates sample volume box. Each probe defaults to a specific range gate.
Doppler Velocity
Scale
Flow direction has a positive and negative indicator, noted in centimeters per
second (cm/sec). When the velocity scale is less than 10 cm/s, it is displayed to the
first decimal point (4.6 rather than 5 cm/s).
