Abstract


In this paper we are aiming to evaluate the feasibility of endogenious motion (induced by heartbeat and vascular activity) of liver to be employed for the tissue characterization in healthy and fibrotic liver. The algorithm based on cross-correlation of ultrasonic RF signals was developed and used for the natural tissue motion assessment. The parameters representing average tissue motion in predefined regions were derived. It was determined that differences in tissue anterograde motion amplitude could be observed for the different severity of liver disease.
