Recently, the innovative product Proton Therapy System of Varian Medical Systems Inc. is approved by China NMPA.

This product is composed of proton accelerator subsystem and treatment subsystem. The proton accelerator subsystem consists of 3 major components: main proton accelerator system, energy selection system and beam transport system. The treatment subsystem contains 3 treatment room, including a 360-degree rotating beam treatment system and Treatment Planning System. The product provides radiation therapy with proton beams for the treatment of solid malignant tumors for all organs and several benign tumors, with specific indications to be determined by clinicians according to the actual situation.

This product is the first approved proton therapy system with superconducting cyclotron and 360-degree rotating gantry. With these technologies, this product is compact in structure with multi-angle treatment function. It can effectively shorten the treatment time for patients while ensuring effectiveness.

The NMPA will strengthen the post-marketing surveillance of the product to protect the safety of medical devices used by patients.
