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 کاملFirst clinical experience in carbon ion scanning beam therapy: retrospective analysis of patient positional accuracy
Our institute has constructed a new treatment facility for carbon ion scanning beam therapy. The first clinical trials were successfully completed at the end of November 2011. To evaluate patient setup accuracy, positional errors between the reference Computed Tomography (CT) scan and final patient setup images were calculated using 2D-3D registration software. Eleven patients with tumors of th...
متن کاملBeam Monitors of Nirs Fast Scanning System for Particle Therapy
At National Institute of Radiological Sciences (NIRS), more than 6500 patients have been successfully treated by carbon-ion beams since 1994. The successful results of treatments have led us to construct a new treatment facility equipped with three-dimensional pencil beam scanning irradiation system. The commissioning of NIRS fast scanning system installed into the new facility was started in S...
متن کاملImpact of Various Beam Parameters on Lateral Scattering in Proton and Carbon-ion Therapy
Background: In radiation therapy with ion beams, lateral distributions of absorbed dose in the tissue are important. Heavy ion therapy, such as carbon-ion therapy, is a novel technique of high-precision external radiotherapy which has advantages over proton therapy in terms of dose locality and biological effectiveness.Methods: In this study, we used Monte Carlo method-based Geant4 toolkit to s...
متن کاملCarbon-ion pencil beam scanning for thoracic treatment – initiation report and dose metrics evaluation
Carbon-ion beam scanning has not previously been used for moving tumor treatments. We have commenced respiratory-gated carbon-ion radiotherapy (CIRT) in the thoracic and abdominal regions under free-breathing conditions as a clinical trial. This study aimed to investigate this treatment in the lungs in comparison with passive scattering CIRT. Five patients had thoracic tumors treated with carbo...
