Patient handling system for carbon ion beam scanning therapy
Our institution established a new treatment facility for carbon ion beam scanning therapy in 2010. The major advantages of scanning beam treatment compared to the passive beam treatment are the following: high dose conformation with less excessive dose to the normal tissues, no bolus compensator and patient collimator/multi-leaf collimator, better dose efficiency by reducing the number of scatt...
متن کاملVerification of Complex 3D-Dose Distributions in Carbon Ion Irradiation
In radiotherapy with swift carbon ions very complex dose distributions are applied to a desired target volume. Up to now at the GSI radiotherapy project only regide target volumes in the skull of patients are treated. Extending the benefit of carbon ion radiotherapy to the whole patients body, problems of target motion as heart beat or breathing will occur. Using raster scan technique this moti...
متن کاملAlgorithms for Biological Dose Optimization in Ion Beam Radiotherapy
From 1997 until 2008 about 440 cancer patients were successfully treated in the ion therapy project at GSI. The patient treatment planning was performed with the software TRiP [1, 2]. A crucial part of the treatment planning is the particle number optimization with the goal to achieve a target dose distribution as close as possible to the prescribed biological dose distribution. The optimizatio...
متن کاملIntrafractional dose variation and beam configuration in carbon ion radiotherapy for esophageal cancer
BACKGROUND In carbon ion radiotherapy (CIR) for esophageal cancer, organ and target motion is a major challenge for treatment planning due to potential range deviations. This study intends to analyze the impact of intrafractional variations on dosimetric parameters and to identify favourable settings for robust treatment plans. METHODS We contoured esophageal boost volumes in different organ ...
متن کاملAssessment of a three‐dimensional (3D) water scanning system for beam commissioning and measurements on a helical tomotherapy unit
Beam scanning data collected on the tomotherapy linear accelerator using the TomoScanner water scanning system is primarily used to verify the golden beam profiles included in all Helical TomoTherapy treatment planning systems (TOMO TPSs). The user is not allowed to modify the beam profiles/parameters for beam modeling within the TOMO TPSs. The authors report the first feasibility study using t...
