Abstract

The present invention relates to devices and methods determining tubular wall properties for improved clinical diagnosis and treatment. Advantageously, tubular wall characteristics are recorded that correspond to the distensibility and compliance of the tubular walls. More specifically, the invention provides for quantitative determination of the pressure wave velocity (PWV) of blood vessels, thereby characterizing, inter alia, the Young modulus, the distensibility, the compliance, and the reflection coefficient of aneurysms, lesioned and non-lesioned parts of blood vessels. The determined properties may be further used to evaluate the degree of calcification of lesioned and non-lesioned parts of blood vessels. These determined values can be calculated and reported in absolute terms as a ratio of the relevant paramater value in the lesion region to the parameter value in a non-lesion region of the same patient.
