The HIMAC clinical study has been conducted with a carbon-ion beam since June 1994. The total number of patients treated as of 2017 was in excess of 10,000. As a new treatment research project, 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-tumor 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-tumor treatment since May 2011, while the moving-tumor treatment since March 2015. In the NIRS-scanning, further, the variable-energy operation from 430 to 56 MeV/u by the HIMAC synchrotron itself has been performed for the depth scanning since September 2015. At the present, a heavy-ion rotating gantry has been developed with the superconducting technology and is in a clinical study stage. As a future plan, we just start “Quantum Scalpel” project. In this project, the LET-painting has been proposed with multi-ions such as oxygen-ion, carbon-ion and helium-ion, which we call an intensity modulated composite particle therapy (IMPACT). Further, we have proposed a super-compact heavy-ion radiotherapy machine utilizing the superconducting technology. This machine consists of a laser ion accelerator as an injector, a superconducting synchrotron with a diameter of around 7 m and more compact superconducting rotating gantry. The recent progress and the future plan of the heavy-ion cancer radiotherapy with HIMAC is reported., 2018 IEEE Nuclear Science Symposium (IEEE_NSS_MI Conference)},
