@misc{oai:repo.qst.go.jp:00065925, author = {Noda, Koji and 野田 耕司}, month = {Jul}, note = {The HIMAC clinical study has been conducted with a carbon-ion beam since June 1994. The total number of patients treated was around 10,000 as of March 2016. As a new treatment research project [1], NIRS has developed both the accelerator and beam-delivery technologies for the sophisticated heavy-ion radiotherapy since 2006, which brings both the static and moving-tumour radiotherapy technologies by the fast 3D scanning. The fast 3D scanning with a pencil beam, which is called NIRS-scanning, has been carried out for the static-tumour treatment since May 2011, while the moving-tumour treatment since March 2015. In the NIRS-scanning, further, the variable-energy operation from 430 to 56 MeV/u by the HIMAC synchrotron itself, instead of energy-degraders, has been performed for the depth scanning since September 2015. At the present, a heavy-ion rotating gantry has been successfully developed with the superconducting technology and is in a beam-commissioning stage. As a future plan, we just start a study of the LETpainting with a carbon-ion beam, which will be realize combining the NIRS-scanning and the rotating gantry. The multi-ions operation will bring more sophisticated LETpainting, which will be realized by a time-sharing operation of the HIMAC accelerator complex. Further, we just start the design study for a superconducting synchrotron with a diameter less than 10 m for more compact heavy-ion radiotherapy machine. The recent progress and the future plan of the heavy-ion cancer radiotherapy with HIMAC is reported., The 12th European Conference on Accelerators in Applied Research and Technology (ECAART12)}, title = {Recent progress and future plan of heavy-ion cancer radiotherapy with HIMAC}, year = {2016} }
