Medical Image Data Generation and Radiotherapy This research area focuses on the production and management of medical image data in diagnostic and therapeutic applications such as virtually assisted surgery. Possibilities for processing and editing medical image data from different modalities, such as computed tomography (CT) or magnetic resonance tomography (MR), by means of software and algorithms, examination protocols and workflow analyses in radiological imaging diagnostics, nuclear medicine and radiotherapy are being examined from a radiological perspective. One focus is the utilization of cross-sectional image data for the visualization and virtualization (navigation and planning) of surgical interventions in the face and skull area. Another focus is placed on the optimization of radiological methods. Quality requirements for new technological applications, especially in diagnostic imaging, are being developed and evaluated.
