We are hiring!

We are currently looking for a PhD student in the field of computational cardiac modeling. Please find the details here and apply before August, 20.

Welcome to the home page of the Institute of Biomedical Engineering at Karlsruhe Institute of Technology (KIT). Since more than 50 years we do research and teaching in the field of Biomedical Engineering.

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

Main focus of the research program of Prof. Dr. Olaf Doessel is the analysis of biosignals from the heart (ECG and electrograms), the imaging of electrophysiological sources in the heart (ECG Imaging), computer modelling of the heart and numerical field calculation in human body.

A second focus is currently established by Prof. Dr. Werner Nahm: it’s the research on optical systems in medicine and life sciences, e.g. new intraoperative applications of Optical Coherence Tomography (OCT) and confocal microscopy in neurosurgery.



Review article "Computerized modeling of the human heart“ published


The next issue of the journal "Zeitschrift für Medizinische Physik“ features a review article on „Computerized modeling of the human heart“ by Olaf Dössel and Axel Loewe from IBT. The „Forum“ paper summarizes the state-of-the-art regarding modeling of cardiac electrophysiology, elasto-mechanics, fluid dynamics, and the circulatory system. Both the potential and challenges of this complementary research approach are discussed.

A computational study about the additional benefit of an ablation catheter with integrated mini electrodes

Radiofrequency ablation has become a first-line approach for curative therapy of many cardiac arrhythmias. In a recent published study, the additional diagnostic benefit of an ablation catheter with integrated mini electrodes was investigated. The computational study showed that catheters with mini electrodes bring about additional benefit to differentiate ablated tissue from nonablated tissue in parallel position with high spatial resolution.

Girls’ Day 2017
Girls’ Day 2017 at the IBT

27th of April 2017. The Girls’ Day took place and the IBT is pleased to introduce the world of Medical Technologie to the visiting girls. 19 girls signed in for our workshop on „Technology in the Hospital - visualizing heart and lung activities“. Content was the electric-impedancetomography, photoplethysmography and the electrocardiography. The short introduction into the methods and the fellowing experiments resulted in a phenomenal feedback. The active participation in our build-in questions and experiments made it a great and funny event. We’d like to thank the organizers, supporters, participants and we are looking forward to the next Girls’ Day 2018!

IBT presents at ECAS in Rome

Phase mapping may provide important information about cardiac excitation dynamics during atrial fibrillation. Both computation and realistic visualisation of this novel parameter were addressed in two presentations by Tobias Oesterlein on the ECAS conference in Rome. By combined assessment of electrogram data and its spatial position, the presented methods allow an improved visualisation of cardiac excitation. This was a valuable addition to talks by the groups of Sanjiv Narayan and Vadim Fedorov, who established the link between electrogram information, optical mapping and resulting depolarisation patterns.

Influence of filtering on the ST segment in the ECG

The so-called ST segment in the ECG plays an important role with the diagnosis of myocardial infarction. In a recent published study, the influence of different filtering methods on the ST segment in the ECG was analyzed. Realistic, simulated ECGs with a region of infarction und known noise were used for evaluation. It became apparent, that methods can influence the ST segment in such a manner that the diagnostic information can be falsified.

Valuable Information Regarding the Interpretation of the Atrial ECG Published

IBT scientists in collaboration with cardiologists from Lund, Sweden identified mechanisms contributing to the ECG of the atria (P-wave). Results regarding the limited contribution of the left atrium and the influence of the site of earliest activation were published in the renowned journal "Europace“ of the European Society of Cardiology (ESC).
