Abstract:
Intra-arterial ultrasonic imaging has several features which affect the feasibility of clinical tissue characterization when compared with trans-thoracic ultrasound. The short distance from transducer to tissue, fluid path, high frequencies, and special characteristics of the tissues of interest all contribute to making practical tissue characterization by measurement of the backscattered signal more probable in intra-arterial imaging. The properties of backscattered ultrasound, and methods of characterizing such signals, are discussed with special reference to intra-arterial applications.
