    Klaus Bratengeier: Adaptive Intensity Modulated Radiotherapy (AIMRT)


    Intensity modulated radiotherapy (IMRT) and its dynamic counterpart, Intensity modulated arc therapy (IMAT), both highly conformal photon techniques, provide the best sparing of the healthy tissue. The interlocking segments from different directions can be regarded as a complex computer assisted three-dimensional puzzle. No single segment can be changed without considering the interdependence with other segments. On the other hand, the dose distributions - tightly tailored to the tumor - are most sensitive to inter-fractional anatomical changes such as delocalization and reshaping. The AIMRT group invents and explores methods to adapt highly complex IMRT and IMAT techniques to the daily target.
