AstemViz - Autostereoscopic medical visualization for minimally invasive surgery

Aims & Objectives

One of the most clinically important heart diseases is the stenoses of the aortic valve, for example due to calcification. For its treatment the Klinik für Herzchirurgie Karlsruhe establishes an innovative minimally invasive surgical procedure, where an artificial valve is patient-friendly placed through a catheter. For the visualization of the operation area, permanent 2D X-ray screening is used.

In this context, AstemViz addresses two major questions: How to acquire more crucial information for pre-surgical planning and how to augment intra-surgical visualization capabilities, inter alia, to 3D. Together with our project partner Tridelity AG, EMCL aims to develop a cutting-edge computing and visualization system which provides supplementary medically relevant information gained by numerical simulations and glasses-free autostereoscopic visualization of the procedure during surgery. The main calculations are implemented and performed with the inhouse-developed multi-purpose finite element software HiFlow³.

Research Topics

To improve the possibilities of the pre-surgical risk analysis we investigate highly innovative methods for an augmented representation of the operation area as well as for numerical simulations of the blood flow and the vascular wall behaviour under pressure. Another crucial field of research is the 2D-3D data fusion of a pre-operative patient model with intra-surgery X-ray screenings. Hereby, optimized methods of scientific computing come into account.


This project is funded by the BMBF.
