چکیده

Carbon-ion radiotherapy is being carried out at Gunma University Heavy Ion Medical Centre (GHMC) since March 2010. A compact electron cyclotron resonance ion source (ECRIS) for GHMC, so-called KeiGM, supplies carbon 4+ ions for treatment. The general structure of KeiGM was copied from a prototype compact source, socalled Kei2. Based on experimental studies for production of carbon 4+ ions with a 10 GHz ECR source at the Heavy Ion Medical Accelerator in Chiba (HIMAC), so-called NIRS-ECR, the field distribution of the mirror magnet for Kei2 and KeiGM was designed. A microwave source with the traveling-wave-tube (TWT) was adopted for KeiGM, with a frequency range and maximum power of 9.75 10.25 GHz and 750 W, respectively. The KeiGM was installed in the GHMC facility in December 2008.

Carbon Ion Radiotherapy at the Gunma University Heavy Ion Medical Center: New Facility Set-up

Carbon ion radiotherapy (C-ion RT) offers superior dose conformity in the treatment of deep-seated tumors compared with conventional X-ray therapy. In addition, carbon ion beams have a higher relative biological effectiveness compared with protons or X-ray beams. C-ion RT for the first patient at Gunma University Heavy Ion Medical Center (GHMC) was initiated in March of 2010. The major specific...

Recent Progress of Heavy-ion Cancer Radiotherapy with Nirs-himac

The carbon-ion radiotherapy (RT) with HIMAC has been conducted since 1994, and the accumulated number of patients treated exceeded 7,500 in July 2013. On the basis of the HIMAC experience, NIRS developed a compact carbon-ion RT facility in order to boost the carbon-ion RT in Japan, and a pilot facility of this work was constructed and conducted at the Gunma University. Toward the further develo...

Impact 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...
