Application of singularity expansion method in estimating size of a stent implanted in the artery

A stent is a metallic structure with meshes used to treat arteries blocked by plaque. The stent´s role is to restore physiologic flow conditions and vascular health. Over-expansion or under-expansion of the stent during implantation in the artery can have serious health risks; thus having a real-time and non-invasive measure of size of stent during implantation is important. In this paper, we propose to apply the singularity expansion method to remotely estimate the size of stent during implantation in the artery.
