This isocentric rotating gantry can transport carbon ions having the maximum kinetic energy of E=430 MeV/u to an isocenter with irradiation angles of over ±180 degrees, and is further capable of performing fast three-dimensional rasterscanning irradiation. By using combined-function superconducting magnets, we could design a compact rotating gantry for CIRT. Construction of the gantry structure as well as the superconducting magnets began since 2013, and installation of the entire rotating-gantry system to the new treatment facility at the National Institute of Radiological Sciences (NIRS) was completed by the end of September, 2015. Beam commissioning subsequently began since October, 2015. After series of the beam commissioning, treatment using the rotating gantry was started since May 2017. We will present an overview of the development for the superconducting rotating gantry}, title = {SUPERCONDUCTING GANTRY FOR CARBON-ION RADIOTHERAPY}, year = {2018} }
