Abstract

For a reliable quantitative assessment of vascular lesions the three-dimensional orientations and connections have to be known accurately. This information can be extracted systematically from two DSA-projections using a digital image processing system. Automatic identification and calculation of three-dimensional coordinates of the vessel centrelines are possible at angles of 15–45° between the two projections. The knowledge of the three-dimensional coordinates allows the determination of the true length and corrected densitometric values of foreshortened vessel sections.
