A method for producing a computational flow dynamics model for assessing the efficacy of the deployment of a flow-diverting device in a blood vessel of a patient is provided. Image data of the patient is acquired with a medical imaging system, from which images depicting the blood vessel are reconstructed. A pre-treatment blood vessel model is generated by segmenting the reconstructed images. This pre-treatment blood vessel model is then used to generate a post-treatment, or post-deployment, model of the blood vessel. A post-deployment model of the flow-diverting device is generated and used together with the post-treatment blood vessel model to generate a computational flow dynamics model.
