Varian Introduces New ProBeam 360° Proton Therapy System

New single-room system features 30 percent smaller footprint than Varian’s previous-generation proton therapy system

Varian Introduces New ProBeam 360° Proton Therapy System

October 23, 2018 — 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.

The 360-degree rotating gantry of ProBeam 360° enables efficient intensity modulated proton therapy (IMPT), and faster treatment times by minimizing patient repositioning and re-imaging, and allowing high-quality CBCT imaging from almost any angle. RapidScan technology, available on the ProBeam 360°, simplifies the process of motion management by delivering each field in a single breath-hold. This capability increases the number of patients who can comply with breath-hold treatments like lung SBRT.

Additionally, Varian's high-definition pencil-beam scanning technology gives clinicians the ability to deliver the dose precisely within the contours of the tumor to minimize dose to healthy tissue. When combined with iterative CBCT, the ProBeam 360° system enables adaptive precision radiation therapy during the course of treatment, helping to make it an even more precise form of proton therapy.

In I-131 cancer therapy, decay events damage sensitive DNA within a tumor cell nucleus, causing catastrophic single and double strand breaks. Clinical use of antibody-delivered Auger emitters could open a window for the targeted destruction of extracellular COVID-19 virions, decreasing the viral load during active infection and potentially easing the disease burden for a patient.
