Figure 2From: A comparison of modelling techniques for computing wall stress in abdominal aortic aneurysms Effect of axial smoothing on the polylines constructed from the CT scans. Model 1 consists of 7 control points, Model 2 has 20 control points, Model 3 has 50 control points, and Model 4 has 70 control points per polylines slice. Green line is the original polyline from the CT scan slice, with the red line being the new smoothed polyline.Back to article page
