Progress report of carbon therapy in i-ROCK

As part of the Kanagawa "Challenge-10-year strategy to cancer" it was decided in March 2005 to establish a carbon-ion therapy system at the Kanagawa Cancer Center (KCC). After about 10 years of this decision, construction of the main building for the acceleration and treatment devices has been started and completed in October 2014. Various treatments for cancer, which include the present photon LINAC for the radiation therapy, will be provided to patients in cooperation with our cancer center hospital. In addition, we will combine a compact dissemination treatment system of carbon-ion therapy to the pencil beam 3D scanning technique designed by the National Institute of Radiological Sciences (NIRS). From December 2015, the treatments were started as a clinical trial. The real treatments have been performed from February 2016 as advanced medical care. In the next step, we plan to treat the lung and the liver cancer using the respiratory gated irradiation technique. In this paper, we report the status of our facility at KCC. (author)
