Doppler Equation<br />
Knowing the Doppler equation is critical:<br />
where:<br />
f Dop<br />
= Doppler shifted frequency (relative to transmit frequency)<br />
f 0<br />
v<br />
c<br />
= transmit frequency<br />
= velocity of target through medium<br />
= speed of interrogating beam through medium<br />
(c = 1540 m/sec for sound in tissue.)<br />
cos(θ) = mathematical correction for angle effect<br />
θ<br />
= insonification angle (or angle to flow)
