Calculate Doppler shift frequency using ultrasound velocity and angle
The Doppler effect is a phenomenon where the frequency of a wave changes as its source moves towards or away from an observer. In medical ultrasound, it's used to measure blood flow and velocity.
The Doppler shift frequency is calculated using the formula: Δf = (2 * v * f₀ * cos(θ)) / c, where v is the velocity of the blood flow, f₀ is the emitted frequency, θ is the angle between the ultrasound beam and the blood flow, and c is the speed of sound in tissue.
Accurate calculation of the Doppler shift is crucial for diagnosing vascular conditions and monitoring blood flow.
