Engineering for Health

Welcome to the web page of the Institute of Biomedical Engineering (IBT) at Karlsruhe Institute of Technology (KIT). For more than 50 years we have been active in research and teaching in the field of biomedical engineering.

In interdisciplinary projects together with medical doctors and medical industry, we investigate new technical systems that help to diagnose diseases earlier and more accurately as well as systems that make therapies more successful.

The main focus of the research program of Prof. Dr. Olaf Dössel is the analysis of biosignals from the heart (ECG and electrograms), the imaging of electrophysiological sources in the heart (ECG imaging). Moreover, we are working on impedance tomography for lung perfusion and hypothermia in stroke patients [more].

The area of research of Prof. Dr. Werner Nahm's group is optical systems in medicine and life sciences. Current projects are focussing on surgical visualization and optical diagnosis [more].

The group of Dr. Axel Loewe develops computational models of the heart and applies them to cardiological problems. We focus on cardiac electrophysiology and elastomechanics to contribute to answer clinical questions such as the genesis of e.g. cardiac arrhythmias and appropriate treatment strategies [more].



An energetic model for the prediction of cerebral temperature decrease in the therapy of stroke patients using therapeutic hypothermia

Hypothermia is often used as an additional therapy to reduce the neurological damage caused by an ischemic stroke. Acandis in Pforzheim, Germany, has developed a new blood cooling catheter for targeted and rapid temperature reduction in the ischemic brain regions while simultaneously avoiding systemic side effects. In order to estimate the achievable temperature range, the cooling time required and the associated decrease in body core temperature when using this new catheter, researchers from the Institute of Biomedical Engineering have developed an energetic numerical temperature model. With this model, the researchers were able to show that under ischemic conditions, the catheter enables a decrease in cerebral brain tissue temperature of approx. 2°C after 30 minutes of cooling. In addition, the simulated effects of blood cooling on the rest of the systemic body were very small.

EMBC 2019
International Engineering in Medicine and Biology Conference

Fifteen participants represented the Institute of Biomedical Engineering from July 23rd to 27th 2019 at the 41st International Engineering in Medicine and Biology Conference in Berlin. Eight posters, five oral presentations and numerous session chairmanships showed Karlsruhe to be a strong competence in the field at the conference edition in Germany. Program chair Olaf Dössel gave the meeting a special character. The broad spectrum of discussed topics amongst scientists from all around the world impressed and motivated the delegation of IBT.

ICIAM 2019
International Conference on Industrial and Applied Mathematics

This conference on applied mathematics with more than 4000 participants takes place every four years, most recently in July in Valencia, Spain. The Computational Cardiac Modeling group was invited to present their work during the minisymposium "Mathematical and Numerical Modeling of the Human Heart“. 
The contribution "The Inverse Problem of Cardiac Mechanics Estimation of Cardiac Active Stress from Endocardial Motion Tracking“ describes first steps towards a novel method to estimate active force generation in the human heart non-invasively.

International Conference on Computational and Mathematical Biomedical Engineering
International Conference on Computational and Mathematical Biomedical Engineering

The conference took place in June in Sendai City, Japan. The Cardiac Modeling Group of IBT presented their work "The Inverse Problem of Cardiac Mechanics Estimation of Cardiac Active Stress from Endocardial Motion Tracking“ as an invited talk in the minisymposium „Mathematical and Numerical Modeling of the Heart Function“.

First German Conference on Research Software Engineering

From June 4-6, the first German Conference on Research Software Engineering took place on Telegraphenberg in Potsdam. The IBT-coordinated SuLMaSS project presented a poster and was signifanctly involved in the organization of the workshop "Challenges for the sustainable development, provision, and maintenance of research software in Germany". Many of the projects that were funded in the scope of the DFG call "Sustainable Research Software" were present and discussed lively during three hours in a "World Café". The results of the workshop will serve as the basis for a whitepaper that will be developed during a DFG round table in autumn. If you are interested in contributing, please get in touch with Axel Loewe.

Collaborative Research Centre „Wave phenomena“ extended

The grant committee of the Deutsche Forschungsgemeinschaft (DFG) decided to extend the funding for the collaborative research centre 1173 „wave phenomena: analysis and numerics“ for 4 more years. Together with our mathematics partners, we work on project B7 "Dynamics of electro-cardiac depolarization waves“. An new aspect to be tackled during the second funding period starting in July will be the coupling of the heart’s natural pacemaker, the sinus node, with the surrounding cardiac tissue.
