Varian announced its new single-room proton therapy system, ProBeam 360°, at the 2018 American Society of Radiation Oncology (ASTRO) annual meeting, Oct. 21-24 in San Antonio, Texas. With a 30 percent smaller footprint than the previous system, ProBeam 360° offers uncompromised clinical capabilities, according to Varian, while reducing vault construction costs by approximately 25 percent. The new system has a 360-degree rotating gantry, a powerful particle accelerator, iterative cone-beam computed tomography (CBCT) imaging and high-definition pencil-beam scanning technology. The system can also provide clinicians a viable path to potential next-generation treatments such as Flash therapy.
