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 کاملExperiments with energy modulated particle beams and biological verification of carbon ion treatment planning
A set of cell survival experiments has been performed in complex fields of therapeutic C ion beams. CHO cells were exposed to the superposition of two or three fields of C ions arranged similar to real patient treatments. Twodimensional survival distributions were measured with our head phantom setup ([1]) and compared with the predictions of our TRiP98 treatment planning system [2]. The planni...
متن کاملAdvanced treatment planning methods for efficient radiation therapy with laser accelerated proton and ion beams.
PURPOSE Laser plasma acceleration can potentially replace large and expensive cyclotrons or synchrotrons for radiotherapy with protons and ions. On the way toward a clinical implementation, various challenges such as the maximum obtainable energy still remain to be solved. In any case, laser accelerated particles exhibit differences compared to particles from conventional accelerators. They typ...
متن کاملMolecular depth profiling with cluster ion beams.
Peptide-doped trehalose thin films have been characterized by bombardment with energetic cluster ion beams of C60+ and Aux+ (x = 1, 2, 3). The aim of these studies is to acquire information about the molecular sputtering process of the peptide and trehalose by measurement of secondary ion mass spectra during erosion. This system is important since uniform thin films of approximately 300 nm thic...
متن کاملComparing experimental assessment of the peripheral dose outside the applicator in electron beams of ELEKTA with Treatment planning system
Introduction: The use of electrons in the electron therapy to destroy tumoral tissue is dedicated significant contribution of different methods of radiation therapy. Scattered radiation due to exited electrons of the applicator affect the dose out of the field in the patient's normal tissue. The aim of this study is to determine the peripheral dose outside the applicator in the...
