Adjusts the angle correction in 1-degree increments (74˚ to -74˚)
between the vertical line of the ultrasound pulse (from the face of
the transducer) and the direction of vascular flow in the sample
volume.
The green line indicates the direction of flow.

You can also adjust the angle by tapping the circle connected to
the Doppler line on the control panel within the B-Mode scout
image and dragging to change the angle.
When the system receives the return signal, it applies an
algorithm to the signal data to correct for the delta. This
produces usable PW Doppler Mode data.
This control adjusts the input signal strength that is mapped to
the spectral display.
To set the Dynamic Range, tap the control to show the flyout.
Adjust the slider to adjust in 1 dB increments or tap the Up and
Down buttons to increase and decrease by 5 dB increments.
Tap Default to return to the system default setting for the current
transducer.

The range allowed is dependent on transducer type.
The setting is displayed on the control for easy reference and
the value is stored with the image.
In PW Doppler Mode and PW Tissue Doppler Mode the dynamic
range applies to the spectral display in the lower window. It does
not apply to the B-Mode scout window.
