4D treatment planning for scanned ion beams
At Gesellschaft für Schwerionenforschung (GSI) more than 330 patients have been treated with scanned carbon ion beams in a pilot project. To date, only stationary tumors have been treated. In the presence of motion, scanned ion beam therapy is not yet possible because of interplay effects between scanned beam and target motion which can cause severe mis-dosage. We have started a project to trea...
متن کاملMonte Carlo-based parametrization of the lateral dose spread for clinical treatment planning of scanned proton and carbon ion beams
Ion beam therapy using state-of-the-art pencil-beam scanning offers unprecedented tumour-dose conformality with superior sparing of healthy tissue and critical organs compared to conventional radiation modalities for external treatment of deep-seated tumours. For inverse plan optimization, the commonly employed analytical treatment-planning systems (TPSs) have to meet reasonable compromises in ...
متن کاملAdvances in 4D Treatment Planning for Scanned Particle Beam Therapy — Report of Dedicated Workshops
We report on recent progress in the field of mobile tumor treatment with scanned particle beams, as discussed in the latest editions of the 4D treatment planning workshop. The workshop series started in 2009, with about 20 people from 4 research institutes involved, all actively working on particle therapy delivery and development. The first workshop resulted in a summary of recommendations for...

no 1: Technical challenges of fast volumetric rescanning O. Actis, D. Meer, A. Mayor, G. Klimpki, S. Psoroulas, D.C. Weber For pencil beam scanning the most studied method to mitigate the dose delivery uncertainties due to the organ motion is rescanning. Achieving an optimal treatment for a moving target by volumetric rescanning, where the whole tumour volume is scanned multiple times, requires...
متن کامل4D geomechanical simulations for field development planning
3D and 4D geomechanical can be time-consuming to build and calibrate. However, once such a model is built, it is relative straightforward to use this model for various field development and management applications. In so doing, the return on the initial investment of time and effort in the creation of a 4D geomechanical model can be substantial. I present a case study where a 4D geomechanical m...
