Wall filter compensation enhances Doppler frequency accuracy despite higher variance; leaves open clinical validation in cardiovascular ultrasound.
A novel method for compensating the bias caused by wall filters in Doppler frequency estimation improves accuracy over noncompensated methods.
Rajaonah et al. (1994) studied this question. Bias compensation method vs. Noncompensated method was evaluated on Bias and variance of the mean Doppler frequency. A method for compensating the bias caused by the wall filter on the mean Doppler frequency improved estimation compared to the noncompensated method, despite introducing a higher variance.
