摘要
Abstract
A weighted spiking filter is proposed for the coded pulse-based ultrasound Doppler blood flow measurement system. Compared with traditional pulse compression filter, this novel method can get better velocity estimation by optimizing the whole system. In a cardiac cycle simulation of pulsatile flow, the mean absolute error and root-mean-square error of this new method are less than those of inverse filter and spiking filter. The results show that the weighted spiking filter has the best pulsatile flow measurement values, while the performance of pulse compression is independent on flow velocity.关键词
