Medical Visualization and Simulation

In The Medical Visualization and Simulation group a series of interdisciplinary researcher work with a range of projects derived from healthcare. We focus on technical aspects of real-time visualization, physics based simulation and image-processing, as well as the clinical validation of the developed application.

Surgical Simulation

This project is focused on real-time simulation of surgical procedures on heart malformations in children, for training and pre-operative planning.
