Conference Series}, month = {Jan}, note = {NIRS has conducted a carbon-ion radiotherapy with HIMAC since 1994. For the progress of the carbon-ion radiotherapy technology, NIRS has developed beam-delivery technologies such as a broad-beam, a pencil-beam 3D-scanning and a superconducting rotating gantry. These technologies have been applied for both the static and moving tumor treatments. Further, NIRS just starts “Quantum Scalpel” project. In this project, a multi-ions irradiation for the LET-painting is studied to obtain the higher treatment efficacy. An ultra-compact heavy-ion radiotherapy machine, with much lower cost, has also been being developed by applying the superconducting and laser technologies for widespread use of the heavy-ion radiotherapy in the world.}, title = {Progress of radiotherapy technology with HIMAC}, volume = {1154}, year = {2019} }
