Abstract
In digital angiography, densitometric information inside the arterial bed are widely used to calculate spatial variations in cross-sectional areas. These measurements are influenced by the orientation of the stenotic segment with respect to the image intensifier. Here, the authors show that these discrepancies can be appreciably removed by a three-dimensional correction using two projection views and a regularization step.
