Varian and HIMC Achieve Milestone with Cyclotron Operation for Proton Therapy in China

Varian has successfully initiated operation of the superconducting cyclotron for its ProBeam® proton therapy system at Hefei Ion Medical Center (HIMC), which marked another major milestone at the new proton center. The cyclotron, a particle accelerator which accelerates protons to two thirds of the speed of light for clinical use, is a core piece of equipment for Varian's ProBeam system.

HIMC will feature three proton therapy treatment rooms with full 360-degree rotational gantries as well as a fixed-beam treatment room and a research room. The ProBeam system is the first in China to offer fully integrated intensity modulated proton therapy (IMPT). The system can also provide clinicians a viable path to potential next-generation treatments such as FLASH therapy.

"We are pleased to achieve this milestone," said Nie Hong, Deputy Director of HIMC, "in the midst of the global COVID-19 pandemic, our fight against cancer should not be slowed. This step moves us closer to completing the center and achieving our goal of providing advanced cancer treatment to 2000 patients a year."

The Proton Solutions team based in Germany leveraged Varian's SmartConnectTM technology to provide support to the onsite engineering team in Hefei. Together they were able to complete beam commissioning, despite limitations with overseas travel.

"It's exciting to see the terrific achievement that HIMC and Varian made in these unprecedented times," said Kolleen Kennedy, chief growth officer and president of Proton Therapy Solutions. "We look forward to our first ProBeam system in China to start treating patients and supporting HIMC in their mission to fight cancer."

Currently 29 leading proton centers have selected the Varian ProBeam proton system, and 13 of the centers are in clinical operation. To learn more about the ProBeam system, visit
