Varian Medical Systems

Varian Medical Systems designs and manufactures advanced radiation therapy equipment—including linear accelerators—and develops integrated software platforms that support the entire continuum of modern cancer care delivery. Now operating as an independent business unit within Siemens Healthineers since its $16.4B acquisition completed April 2021, it remains headquartered in Palo Alto with global reach across more than 70 locations worldwide, serving hospitals, cancer centers, and research institutions. Their product portfolio spans commercialized solutions such as Halcyon radiotherapy system, Ethos adaptive platform, and recently FDA-cleared IntelliBlate microwave ablation device. Various acquisitions have expanded their capabilities into interventional therapies (Sirtex, CyberHeart). The company’s mission continues to be centered on defeating cancer through technological innovation while maintaining strong ethical leadership rooted in its founders’ legacy.
