Dynamic inverse problems
Inverse problems arise whenever a searched-for quantity cannot be directly observed but has to be extracted indirectly from measured data. Classic examples constitute imaging modalities such as computerized tomography which provide information about the interior of a patient or an object in a non-invasive way.
The classic regularisation theory is based on the assumption that the searched-for quantity is stationary during the acquisition. However, in many applications from medicine to non-destructive testing, this assumption is not satisfied. Therefore, we work on the development and (numerical) analysis of time-dependent regularization methods which incorporate the dynamics of the object.
Imaging and tomography
Developing new methods in imaging and new fields of applications necessitates novel approaches in mathematical modelling, data processing and image reconstruction. A special focus of our group lies in this respect on computerized tomography and magnetic resonance imaging.
Data analysis and image processing
In order to extract features and properties of the studied medium, the reconstruction results are typically subject to further processing steps. Since an ever-increasing amount of data arises in modern applications, special algorithms are required to extract the desired infomation in an efficient and stable way.
