In just a few seconds, the 3D model is calculated and displayed showing an overview of quantification results, including information about vessel diameters and length. The 3D image eliminates the foreshortening effect that occurs with two-dimensional images, enabling more accurate length measurements. It allows the diameter profile and related parameters, such as degree of stenosis and reference vessel diameter, to be identified with greater precision than is possible with a single projection. That is particularly valuable for selecting appropriate stent lengths and diameters for deployment. It also provides bifurcation data for support in selecting the appropriate stenting technique.
