Tissue chracterization of coronary plaque based on fractal analysis

Abstract

A precise tissue characterization of coronary plaque based on fractal analysis by using radiofrequency (RF) signal is proposed. The RF signal is obtained by intravascular ultrasound (IVUS) method, which is used for the diagnosis of the acute coronary syndromes (ACS). In the proposed method, the RF signals reflected from the different tissues are supposed to have the different complexities. The effectiveness of the proposed method is verified by a series of experiments using IVUS RF signals obtained from the coronary arteries of a rabbit and a patient.
