Computational Patient Models

Dr. Kristina Giske
Research Group Leader
Our team is shaping digital patient twins tailored for radiotherapy. At the interface of advanced imaging, biophysical organ and tissue modeling, and artificial intelligence we explore subtle treatment responses using spatio-temporal-resolved in-silico patient replicas.

We are physicists, medical informaticians, data scientists, mathematicians, and radiooncologists working together for the benefit of the patient.
Our research is dedicated to in-silico radiotherapy simulation of cancer patients undergoing curative irradiation treatment. The first challenge for technically precise radiation therapy lies in adapting dose delivery to deformations in the patient’s anatomy induced by motion and physiological changes. The second challenge is to detect subtle changes in longitudinal imaging, which allow to test treatment outcome prediction models.
Our vision is to create a virtual patient model, serving as a proxy for treatment simulation by accumulating the physical dose and predicting the therapeutic effect of the planned treatment. This together empowers treating physicians to tailor the treatment to the specific needs of the patient before irradiation and during the treatemtn course. In-silico model development, advancements in imaging and computer technology, and our passion for unusual solutions are our tools in the fight against cancer.
