Overview

The course will introduce techniques of modelling and simulating human tissue for medical applications. The course includes basic and advanced techniques of segmentation, registration, reconstruction and motion simulation in medical applications from disease detection to surgery simulation and surgery in virtual reality. This tutorial introduces various methods along with concrete clinic cases and present examples to convert research work to commercial applications.

Welcome and Introduction

    After the introduction of the presenters of this tutorial, we will present several several applications of virtual medicine as appetizers for the whole tutorial. In particular, this will include virtual endoscopy, Cardiac Time Volume Analysis, Time Density Analysis, and functional MRI.

Foundations

    In the second session, we will focus on fundamental methods and techniques for the acquisition and processing of medical data. Specifically, we will talk about medical imaging techniques, segmentation, classification, image registration and fusion, navigation with and rendering of medical data. Specifically, the latter topics will be in the context of virtual endoscopy and hardware-accelerated methods.

Applications of Virtual Medicine

    After learning about the basic techniques required for virtual medicine, this talk will focus on existing virtual endoscopy systems and on support system for surgery. Furthermore, we will briefly talk about distributed virtual medicine. (The first part will actually start right after the foundations session.)

Motion Simulation

    This session will present techniques for the simulation of the motion of a hip joint using dynamic Magnetic Resonance Imaging (MRI).

Soft-Tissue Simulation

    In the final technical session, we will discuss the physical and mathematical foundations of the various techniques for soft-tissue modeling.

Questions and Answers

    While there will be time during the various presentations for questions, we also provide this dedicated questions and answers session.

Prerequisite and Intended Audience

We assume a basic understanding of 3D graphics, visualization and medical-imaging technology. Although recent research results will be presented, we are not in particular targeting at experts in the field.
