Determining Flow Direction<br />
Like spectral Doppler, the color direction is easily determined by<br />
analyzing the angle formed between the steered beam and the flow<br />
direction.<br />
+ V, + f Dop<br />
Angle less<br />
than 90º<br />
Flow Direction<br />
- V, - f Dop<br />

* The angle to flow is always measured between the steered beam<br />
direction and the head of the flow (where the flow is going to)
