Abstract

This paper addresses applying the wavelet transform to cross correlation (CC) processing in pulsed-wave (PW) ultrasound for measurement of tissue motion and the velocity profile of blood flow. Cross correlation processing, has certain advantages over the Doppler method in performance, but its performance is sensitive to window size and noise. We describe how CC processing can be done with the wavelet transform. We discuss that because the wavelet transform has a unique of feature of varying time-frequency resolution, cross correlation processing in the wavelet domain is more robust with window size and less sensitive to noise.
