Abstract
Ahrracr-We investigate the acoustic characterization of infinite cylindrical fluid shells and its application to ultrasonic diagnostic of blood vessels. The rigorous solution of the direct problem, i.e., a cylindrical shell, whose parameters are known, illuminated by an incident plane wave, is studied first. Then it is extended to the case where the incident wave is limited and characterized by a Gaussian profile. The rigorous solution is compared to an approximate one whose analytical exy :ession is very simple while describing accurately the field. The approximate solution will permit very simple relations to be obtained between the scattered field and the shell parameters and thus to assess some of these from the multistatic study of the backscattered field in a limited space.
