Real-time 3D Shape Instantiation from Single Fluoroscopy Projection for Fenestrated Stent Graft Deployment.

Robot-assisted deployment of fenestrated stent grafts in fenestrated endovascular aortic repair (FEVAR) requires accurate geometrical alignment. Currently, this process is guided by two-dimensional (2-D) fluoroscopy, which is insufficiently informative and error prone. In this letter, a real-time framework is proposed to instantiate the 3-D shape of a fenestrated stent graft by utilizing only a si...
