From OCT imaging to virtual stent implantation. (a) 3D reconstruction of lumen and 2D slices of artery wall from OCT data (top). Reconstruction of centerline and artery radii r (bottom). The culprit lesion is highlighted with a yellow circle. (b) Initial (left) and final (center) configuration of the virtual stent expansion. The right image shows a close-up of the deformed stent, where the initial stent centerline geometry is indicated with the black curve. The stent is modeled with 1D structural beam elements and is visualized with rectangular cross-section. The color bars show the norm of the structural displacements of the artery wall, \(\varvec{d}_w\), and of the stent crown, \(\varvec{d}_s\), respectively. (c) Post-processing of the artery and stent geometry, where the full 3D stent geometry is intersected with the deformed inner surface of the artery.
