Ion beams in radiotherapy - from tracks to treatment planning

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...

Treatment Planning for the Carbon Ion Radiotherapy

In the three therapy beam times 2007 about 50 patients were planned and treated with our treatment planning software, TRiP98, and its development version, TRiP98BEAM. In the past, the standard method was to optimize the biological target dose distribution for the contributing partial fields singly. Due to the enormous effort for the computation of biological effects, only a simple, but still su...

Radiotherapy treatment planning

In radical radiotherapy treatment we aim to accurately deliver a lethal dose of radiation to tumour cells while sparing any surrounding normal tissues. Radiotherapy treatment planning is the process undertaken to determine the most appropriate way to deliver the radiation in order to meet the clinical prescription. Rapid advances in technology and computing, particularly in relation to imaging,...

Dosimetric comparison of carbon ion radiotherapy and stereotactic body radiotherapy with photon beams for the treatment of hepatocellular carcinoma

BACKGROUND The purpose of this study was to compare carbon ion radiotherapy (C-ion RT) and stereotactic radiotherapy (SBRT) with photon beams for the treatment of hepatocellular carcinoma (HCC), specifically with regard to the dose volume parameters for target coverage and normal tissue sparing. METHODS Data of 10 patients who were treated using C-ion RT with a total dose of 60 Gy(RBE) in fou...
