A New Method for Doppler Clutter Rejection Based on Irregular Sampling and Iterative Spline Reconstruction
IEEE SIGNAL PROCESSING LETTERS, VOL. 11, NO.9, pp. 764-767, 2004，-0001，（）：
The low frequency and high amplitude clutter signal constitutes a great disturbance for the discrimination of low velocity blood flow signals in a Doppler ultrasound measurement system. In this letter, a novel method for clutter rejection is proposed, incorporating irregular sampling and iterative reconstruction of cubic spline. Experimental results indicate this approach outperforms the traditional way of high-pass filtering with its effective elimination of clutter and preservation of low velocity blood component in the overlapped frequency region.
