Radiation oncology technology leader providing TrueBeam linear accelerators, radiosurgery systems, and AI-driven treatment planning software.
Varian Medical Systems is a radiation oncology technology company founded in 1948 as Varian Associates by Russell H. Varian and Sigurd F. Varian, and headquartered in Palo Alto, California. The company designs, manufactures, and sells medical linear accelerators, treatment planning software, and oncology information systems used in cancer radiotherapy centers across more than 100 countries. In April 2021, Siemens Healthineers completed its acquisition of Varian for approximately 16.4 billion US dollars, after which Varian continued operating under its own brand while benefiting from Siemens Healthineers' global sales and service infrastructure.
Varian's flagship product, the TrueBeam radiotherapy system, is an advanced linear accelerator platform engineered to deliver high-dose radiation to tumors in the head and neck, lung, liver, breast, and abdomen with submillimeter precision, expanding treatment options for challenging and motion-affected cases. In February 2024, Varian received FDA 510(k) clearance for the TrueBeam system incorporating the HyperSight imaging solution, which enhances real-time imaging guidance during treatment delivery. The company also manufactures the ProBeam Proton Therapy System, an all-pencil-beam-scanning intensity-modulated proton therapy platform developed in collaboration with the Paul Scherrer Institute in Switzerland, featuring a 360-degree rotating gantry and iterative cone-beam CT imaging.
Varian's RapidArc volumetric arc therapy technology delivers a full three-dimensional dose to a tumor in under two minutes using a rotating gantry in single or multiple arcs, including gated delivery to compensate for respiratory motion in lung and abdominal tumors. At ASTRO 2024, Varian introduced RapidArc Dynamic as an optional feature for the TrueBeam 4.1 delivery platform paired with the Eclipse treatment planning system; early research indicated the technology can reduce organ-at-risk dose by up to 50 percent, accelerate plan optimization and dose calculation by up to 70 percent, and reduce the number of treatment arcs by as much as half. Varian's ARIA oncology information system supports integrated workflow management across radiation therapy, medical oncology, and cancer survivorship programs, and was highlighted alongside imaging innovations at ASTRO 2024 for enabling more personalized patient care pathways.
