Fig. 5.

Stenosis quantification using the commercial stenosis quantification software and conventional SECT angiographic data. The yellow lines on the grayscale maximum intensity projection (MIP) images (far left of each panel) mark the location of the stenosis, whereas the green and red lines mark the reference locations where a stenosis is not present. The software reported a one-dimensional vessel profile as well as the percent area stenosis relative to the reference location (red rectangular boxes).
