Ultrasound Tissue Harmonic Imaging based on Wavelet Correlation Analysis

Abstract

In this paper, an ultrasound tissue harmonic imaging method based on wavelet transform has been proposed. Wavelet transform is utilized to analyze the correlation between mother wavelet and the received echoes. In order to obtain a better correlation, a new mother wavelet named ‘Tissue wavelet’ is constructed according to the KZK equation. The proposed method was validated by experiments performed on an ultrasound flow phantom. Results showed that the contrast and axial resolution have been improved effectively.
