Real Time Images of Local Ultrasonic Spectral Parameters for Tissue Differentation Through Wavelet Transform

In this work we propose a novel echographic method to investigate biological tissue internal organization and consequently to differentiate pathological regions. The method is based on time-frequency processing of the radiofrequency echographic signal. Our analysis correlates spectral parameters to actual organization and mechanical properties of investigated tissue and, clinically, to physical properties of tissue derived from histology.
