Proton beam therapy is a new kind of radiation therapy based on proton beams accelerated into high energy.
When a proton beam enters the human body, it comes to a complete stop upon reaching a certain depth. At that time, the proton loses much of its energy (see *1). This allows radiation to be concentrated on a target focus of disease. Consequently, proton beam therapy is in the spotlight as a therapy with less side effects than conventional X-ray therapy and lower impact on the body than surgery.
Control of a synchrotron accelerator that accelerates proton beams up to a maximum of 250 MeV.
Beam transport control where accelerated proton beams are extracted and efficiently transported to each therapy room.
Operation monitoring of the entire device, monitoring and control of the sequence of therapeutic irradiation.
The system is multiplex and redundant according to the importance of specific phenomena. It is safely designed independently from the control system.
