The aim of this thesis was to investigate the feasibility of quantitative arterial tissue characterization from ultrasonic puis-echo measurements, acquired with an intravascular ultrasonic catheter (30 MHz). Two major complications, that arise in an attempt to perform quantitative tissue characterization were investigated. These complications were the angle dependence of the backscatter intensity and the effect of the presence of blood in-vivo on the image quality. The study consisted of three parts. The first part (Chapter II) deals with the quantitative effect on the backscatter power of the angle of incidence of the ultrasonic beam with respect to the arterial wall. Iu the secoud part of the study (Chapters III and IV) the acoustical behaviour of blood was investigated. Finally in the third part (Chapter V) the backscatter behaviour of both arterial tissues and blood was simulated on the basis of general acoustic theory. Before these subjects are reponed, a shon survey on the morphology of the arterial wall and the propenies of blood is given in the introduction (Chapter I).
