Varian Medical Systems’ mission is to focus energy on saving lives. To meet this challenge, we equip the world with new tools for fighting cancer, taking X-ray images, and protecting ports and borders.

Since the 1950s we have been producing tools that harness the power of X-ray energy to benefit humankind. In recent decades, we have pioneered developments in the fields of radiotherapy, radiosurgery, X-ray tube technology, digital image detectors, cargo screening, and non-destructive testing. We have a robust product portfolio, and long-standing relationships with many of the world’s leading clinicians and manufacturers of industrial and medical imaging systems. As Varian continues to grow, our staff of over 6,500 people in 70 sales and support offices around the globe is developing innovative, cost-effective solutions that help make the world a healthier, more secure place.
