Fluid mechanics of cerebral aneurysms and effects of intracranial stents on cerebral aneurysm flow

Luca Augsburger

This thesis focuses on intracranial aneurysms and particularly on the effect of blood flow in the three major phases that characterize an aneurysm: initiation, growth and rupture. As it stands today, blood flow is the major driver of this disease. The unde ...

A Computer-Based Real-Time Simulation of Interventional Radiology

Hannes Bleuler, Lindo Robert Duratti, Fei Wang, Evren Samur

Interventional radiology is a minimally invasive procedure where thin instruments, guidewires and catheters or stents are steered through the patient’s vascular system under X- ray imaging for treatment of vascular diseases. The complexity of these procedu ...
