Recent studies show that placement of neurovascular stents during treatment procedure plays a vital role in modifying the hemodynamics in aneurysm sac and parent vessel. This study proposes an improved fast virtual stenting method for stent deployment, which can be used in treatment planning by comparing different treatment strategies. This method is built upon the FVS[1] method by Larrabide et al., which expands the stent within blood vessel by providing artificial mathematical forces. Current method incorporates two innovations: an improved initialization of the stent and an advanced collision detection method between parent vessel and stent to prevent stent from going out of the vessel. These improvements enable this method to deploy stents within time comparable to clinical surgical procedure and help clinicians in quick decision-making during treatment strategy.
