Physical dose conformation
We explore and develop radiation treatment techniques for optimum physical dose conformation to the tumor target volume. Our efforts are focused on proton radiotherapy and advanced photon treatments, as well as on their comparison.
As a basis for treatment optimization we work on a variety of modeling projects including relative biological effectiveness in proton therapy, outcome models for the relationship between the dose distribution and clinical outcome, and spatial modeling of microscopic disease for gliomas.
Intensity modulation is crucial both in photonradiotherapy (IMXT) and in proton radiotherapy (IMPT). In particular, we develop robust optimization methods for handling uncertainty in IMPT, direct aperture optimization algorithms, VMAT plan optimization, and multi-criteria planning methods.
We develop concepts and methods to consider the time component in the whole radiotherapy chain, from imaging over planning and optimization to treatment delivery.
To increase the precision of the dose application we develop new targeting techniques. To increase the accuracy of the dose prediction we perform Monte Carlo simulations.
