May enhance pulsed Doppler velocity estimation accuracy; leaves open clinical cardiovascular validation.
A new discrete time domain Doppler frequency estimator provides nearly unbiased estimates of mean frequency and can increase the range-velocity product of pulsed Doppler velocity meters.
Angelsen et al. (1983) studied Ultrasonic Blood Velocity Measurements. Discrete time Doppler frequency estimator was evaluated on Mean frequency of the signal spectrum. A new discrete time Doppler frequency estimator provides a nearly unbiased estimate of the mean frequency of the signal spectrum, allowing an increased range-velocity product for pulsed Doppler meters.
