Question

If you obtain a peak velocity of 60 cm/s with the Doppler correction angleset to 60 degrees and you change it to 0 degrees, what is the displayedvelocity in the vessel

Answer 1

Explanation:

Assuming that the velocity profile is constant throughout the vessel, the displayed velocity in the vessel can be calculated using the Doppler equation:

V = Vp × cos(θ)

where Vp is the peak velocity measured by the Doppler ultrasound and θ is the angle between the Doppler beam and the direction of blood flow.

Given that Vp = 60 cm/s and θ = 60 degrees, we can calculate the displayed velocity in the vessel when θ = 0 degrees:

V = 60 × cos(0) = 60 × 1 = 60 cm/s

Therefore, the displayed velocity in the vessel when the Doppler correction angle is set to 0 degrees is 60 cm/s.
