Patient-Specific Vascular Modeling

The morphology of cerebral arteries and cerebrovascular diseases
vary greatly among individuals. Therefore, it is helpful to construct a
vessel model of cerebral artery for each patient based on individual
information and apply it for preliminary simulation of endovascular
intervention. In this chapter, we propose a technique for constructing
a vasculature model by using individual information obtained with
computed tomography (CT) and magnetic resonance imaging (MRI).
Several vasculature models of actual cerebrovascular diseases are
constructed by using the patient-speciic modeling method. Then the
proposed vascular model is evaluated by simulating endovascular
intervention procedures within this model, and the performance
and utility are discussed from the viewpoint of clinical use. Finally
we present a simulator including major vasculature models that
achieves the comprehensive simulation of endovascular intervention
by integrating the technologies proposed in this chapter, and then its
utility is evaluated by a survey.

3.1 Introduction and Background

Recently established endovascular intervention is a potent treatment
modality for various vascular diseases, which reduces the invasiveness
for patients. Many devices for endovascular intervention have been
developed since late 1980. The most prominent advancement was
