Multiphysics Simulation and Advanced Signal Processing
Our group pursues the goal of improving MR imaging and spectroscopy through customized, intelligent hardware systems.
Our work focuses particularly on improving measurement sensitivity, shortening examination times, and enhancing patient well-being and safety.
We develop innovative concepts for radiofrequency coils and work on technical solutions for the wireless transmission of coil signals. In addition, we investigate the integration and safety of supplementary sensors and devices within MRI scanners – also using numerical simulations. We further design and build specialized phantoms for specific MRI applications, such as a torso motion phantom.
Through science communication initiatives and the release of open-source datasets, we aim to make our research accessible to a broader public.
Our team is constantly searching for new members. Contact Roberta Frass-Kriegl if you are interested!
