Welcome to the Institute of Biomedical Engineering and Informatics at the TU Ilmenau

The Institute of Biomedical Engineering and Informatics (BMTI) is working in the field of research and development of technique-oriented methods and systems for early detection, diagnosis, therapy and rehabilitation in medicine. The BMTI was certified according to the "System der Qualitätssicherung in der Ausbildung der Gütegemeinschaft der Medizintechnik (GGMT)" and is the first educational institution receiving the RAL seal of quality. The new bachelor and master degree programs "Biomedical Engineering" were introduced in the year 2005. Biomedical Engineering is technology for life. In cooperation with medical partners it directly affects the human health and develops new methods for detection and treatment of diseases and implements them in medical technologies.

The TU Ilmenau has a long and successful tradition in the field of biomedical engineering. Already in the year of 1953 the Institute of Electromedical and Radiological Engineering was established at the former “Hochschule für Elektrotechnik” (HfE), which was the first university institute in Europe that introduced an on-campus program of Biomedical Engineering.

The novel flexible cap, setup C (left) and the electrode configurations of the conventional application system, setup R (right) on a head model. The inset in a depicts the inside of the cap with the textile electrodes exposed. Bottom: Histograms of participants’ responses on the evaluation of comfort (n = 60).

Transcranial electrical (current) stimulation (tES) is a non-invasive technique to modulate neuronal activity. Conventional tES applications build on rubber electrodes embedded in sponge pockets soaked with saline solution and fixated by rubber bands. more

Geometries of the single-channel MRI setup at PTB (A) and the multi-channel MRI setup at Aalto (B). The illustrations include the polarizing coil (red), the receiver coils of the sensors (blue), the head model (gray), and the stimulation electrodes (black). C: Model positioning in the MRI coordinate system. The plane between the electrodes corresponds to the slice in D and E, showing the reconstructed magnetic field (D) and the reconstructed current density (E).

Magnetic fields in combination with currents flowing in the tissue can be measured non-invasively by ultra-low field magnetic resonance imaging (ULF-MRI) and enable current density imaging (CDI), which may be used for conductivity mapping of human head tissue. In this study, the relationship between the signal-to-noise ratio in the MRI image and field reconstructions. more
