Multiphysics Simulation and Advanced Signal Processing
Our group pursues the goal of improving MR imaging and spectroscopy through customized, intelligent hardware systems.
In particular, the sensitivity, shortening the duration of examinations and the well-being and safety of patients are our focus.
We explore new concepts for radiofrequency coils as well as technical solutions for the wireless transmission of coil signals. We are testing the usability and safety of additional sensors and devices in MR scanners and, in this context, also work with numerical simulations. In addition, we are developing phantoms for special MR applications, such as a torso motion phantom.

Our team is constantly searching for new members. Contact Roberta Frass-Kriegl if you are interested!
