Development of Next-generation Heavy-ion Radiotherapy System (Quantum Scalpel)
To reduce the size and improve the performance of heavy-ion radiotherapy system, we are conducting research and development of a next-generation heavy ion radiotherapy system consisting of a multiple-ion source, a compact linear accelerator, a superconducting synchrotron, and a superconducting rotating gantry. The synchrotron uses a superconducting electromagnet to reduce the area to about 1/17 that of HIMAC. In addition, the multiple-ion source can output multiple highly charged ions from helium to neon and can switch ion species within one minute.
