A Company of Firsts

Since its inception over 50 years ago, Varian has been known as a company of firsts - the first klystron microwave power source, the first standing wave medical linear accelerator, the first Vaclon pump, and much more. This success has been made possible through Varian's unique ability to attract some of the world's finest talent and to foster an atmosphere of innovation and creativity. Varian's focus on innovation is evidenced by the 188 patents the company holds worldwide. Another 146 patents are currently pending. Today, Varian is still a company of firsts, with a portfolio of cancer therapy hardware and software that is making a major difference in thousands of lives.

CLINAC MEDICAL LINEAR ACCELERATOR Since commercializing the first standing wave medical linear accelerator, Varian has been at the forefront of advances in radiotherapy systems. Varian medical linear, accelerators incorporate 120 LEAF MULTILEAF COLLIMATOR Varian's 120 MultiLeaf Collimator, the only one of its kind in clinical use, allows the highest resolution treatment ever. With this sophisticated beam-shaping device clinics can deliver discrete doses to areas as small as 2 mm x 5 mm, and conform treatments to tumors of any size or shape. INTEGRAL HOUSING TUBE Varian has introduced patented innovations into high performance X-ray tube technology, substituting tungsten for lead in the housing and using air rather than oil to cool the tube. These advances make Varian's Integral Housing Tube less costly, safer, more durable, easier to use, lighter, smaller, quieter, and friendlier to the environment, ADVANCED CT SCANNER TUBE Varian developed the most powerful tube on the market for high-resolution, high-speed CT scanning. It is capable of completing a scan in just half a second to generate high quality diagnostic images. SYSTEM INTEGRATION Generation 6 is the world's first and only fully-integrated system from a single supplier for managing all aspects of external beam radiotherapy. The Gen 6 software architecture ties together treatment planning, treatment delivery and simulation, information management, verification for quality assurance, and department administration.

technical innovations that make them the most reliable and versatile in the world. Today, more than 3,000 Varian systems are in service around the world, treating an estimated 1,000,000 cancer patients each year. ...................................... RESPIRATORY GATING The Respiratory Gating System adds a new level of precision to radiation therapy. The first commercially available system of its kind, it makes cancer radiotherapy more accurate and effective by adjusting beam delivery for tumor movements caused by breathing. The Varian system "gates" or turns on the radiation beam only when a targeted tumor is within a prescribed area. a-Si FLAT PANEL IMAGING The amorphous silicon flat panel image detection unit acquires both fluoroscopic and radiographic images on the same receptor and displays them digitally, eliminating the need for X-ray film. This technology is at the center of Varian's portal imaging product, which enables clinicians to instantly evaluate IMRT treatments and ensure that radiation beams are targeted correctly. It is also being used in other medical applications and for inspection in industrial settings.
