Manufacturing Patient-Specific Phantoms to Treat Aneurysms Using Rotational Angiography and 3-D Modeling

The purpose of this study is to manufacture a patient-specific phantom containing multiple aneurysms that can be observed and tested to determine the need for interventional treatment. The vasculatures for the phantoms are taken from unhealthy individuals using rotational angiography as part of a stroke study. Different neurovascular sections exhibiting aneurysms from five patients were combined into a single Circle of Willis with 3D modeling software. Physicians and investigators can use this phantom to test treatment options, such as catheter interventions involving stents and coils.
