Important parameters in quantitative coronary angiography (QCA) are the severity and length of the lesion, the radius of the nonstenotic part of the affected vessel segment and the bifurcation angle (in the case of a bifurcation lesion). Unfortunately, QCA results can be influenced by the viewing angles corresponding to the angiographic images used to(More)
In clinical practice, the quantification of stenotic lesions in coronary arteries is mostly done using angiographic images of the coronaries. This method is called Quantitative Coronary Angiography (QCA). Unfortunately, the QCA results depend on the viewing angles corresponding with the used images. To deal with this problem, multiple computer systems have(More)
In cardiac catheterization labs, x-ray angiography is used to visualize abnormal narrowings of the coronary arteries, i.e., stenoses. An often used technique to treat stenoses is stent implantation. This technique can only be performed successfully if the length of the stenotic lesion and the radius of the non-stenotic part of the narrowed vessel segment(More)
