Abstract: Technologies as described herein are directed towards generating optimized stent designs for treatment of tubular anatomical structures. In an exemplary computing system, the system obtains imaging data comprising images representative of anatomical structures. The system then generates a plurality of models based upon the imaging data. The models are then clustered based upon similar characteristics of the models. Certain fit parameters are applied to the models in each cluster and an optimized stent shape is generated for each cluster, wherein each optimized stent shape is representative of the models within the cluster.
