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].



How do physicians and digital technology collaborate in 2035?

The VDE "Praxisnetz Digitale Technologien“ and the "Deutsche Gesellschaft für Biomedizinische Technik" (DGBMT) published a future scenario under participation of IBT experts:

„In the year 2035, digital technology and in particular artificial intelligence have overcome most regulatory obstacles. They expanded into virtually all areas of the public health sector and markedly changed the working environment of physicians. Similar to earlier developments in other professions like pilots, physicians experience a symbiotic collaboration with technology in their daily routine...“

IBT successful at BMT 2019 in Frankfurt

Twelve members of IBT were attending BMT 2019, the joint annual conference of the German, Austrian and Swiss Society for Biomedical Engineering, and presented results of their research work to the community. Claudia Nagel was awarded the 1st prize in the student competition for presenting results of her Master's thesis. Rosa Daschner was awarded the 5th prize for presenting the results of her Bachelor's thesis.

Rätsel Herz
Mystery of sudden cardiac death of dialysis patients solved?

Dialysis patients have an unexplained high risk to suffer sudden cardiac death: up to 100x higher than patients with normal kidney function. A simulation study of IBT suggests a potential reason: the natural pacemaker of the heart, the sinus node, reacts very sensitive to changes of the calcium concentration in the blood. In collaboration with researchers in Bologna (Italy), Szeged (Hungary), Monza (Italy), and New York City (USA), we could show that the heart beat slows down upon a decrease of the calcium concentration. In extreme cases, the heart beat stops. As calcium and other ion concentrations (such as potassium) undergo massive fluctuations in dialysis patients, this could be a relevant reason for the extreme risk of sudden cardiac death in these patients.

Robust method to determine atrial wall thickness

In collaboration with researchers from Auckland (New Zealand), Ohio (USA), London (Canada), and Freiburg (Germany), IBT researchers have published a novel algorithm to reliably determine the wall thickness of the two atria of the heart. Based on medical imaging data, two coupled partial differential equations are solved. From the solution, the atrial wall thickness can be extracted for every point on the surface of the atria. The efficient new method is more accurate and robust than previous approaches and can in future be used to guide ablation therapy for atrial fibrillation and flutter.

iHeart 2019
RISM Congress 2019

The RISM Congress, iHeart - Modeling the Cardiac Function, in Varese Italy, 22-24 Juli 2019, was visited by a member of the IBT Computational Cardiac Modeling group. There the work "A Method for Pressure-Volume-Based Parameter Identification for a Passive Constitutive Model of Myocardium“ was presented in a posterblitz-session.
