Paper Abstract

The hemodynamics of an arterial stenosis are of great diagnostic importance and mainly depending on the absolute dimensions of the vascular lesion. Therefore, it is important to get the true vessel borders from angiographic film. In this study the effect of various conditions on the re-presentation of model coronary arteries on angiographic film is presented. A series of model coronary arteries consisting of silicone rubber tubings with different inner diameter from 1.0 to 3.8 mm and different wall thickness from 0.3 to 1.0 mm were angiographied at 25 f/sec. Urografin 766 in concentrations from 30 to 100 % was used for perfusion. The cinefilms were digitized by manual tracing of the vessel borders and were quantitatively analyzed with a PDP 11/34 minicomputer. It could be shown that the studied conditions had an effect on edge detection, and therefore on estimation of stenosis geometry. It is concluded that automated image processing systems should be tested for their accuracy not only with brass models, but with more realistic models under conditions simulating coronary angiography.
