Varian Medical System's Products:
Varian offers many different types of advanced radiation treatment systems that provide specific treatment and patient care. Varian’s systems can be easily modified and upgraded depending on the clinical needs.

Current Products:

 * Halycyon System- Varian’s newest cancer treatment machine, made to simplify and better image-guided volumetric intensity-modulated radiotherapy. Can be used in standard vaults but also in smaller, lightly shielded rooms.
 * Edge Radiosurgery System- The Edge radiosurgery system revolutionizes the way advanced radiosurgery is delivered. Capable of both photon and electron energies.Can treat many types of cancers including lung, brain and spine.
 * TrueBeam Radiotherapy System- The TrueBeam platform system is a fully-integrated system for image-guided radiotherapy and radiosurgery. Allows for customization of energies and additional capabilities.


 * Varian's TrueBeam radiotherapy machine.


 * VitalBeam Radiotherapy System- The VitalBeam’s Maestro control system synchronizes a monitoring system that treat advanced cases accurately. Uses x-ray technology to treat all parts and organs of the body.
 * Clinac iX System- The high performance Clinac system is a reliable accelerator designed to deliver a wide range of imaging and patient treatment options. Built on a analog and digital platform.
 * Proton Therapy- Varian's proton therapy delivers the radiation exactly where it is needed. Due to increasingly sophisticated imaging, delivery and scanning techniques, the options for treatment by proton therapy continue to expand around the globe.

Varian Medical System’s Acquired Companies:

In February of 2018 Varian Medical Systems announced that it bought a private Canadian based company called Evinance Innovation which specializes in clinical decision support software. Evinance Innovation will help further Varian’s 360 Oncology care management platform by integrating scientific workflow and decision support. With this integration patients and doctors can make better planned decisions for future treatments. This acquisition is the latest step in Varian's long-term strategy to become a global leader in multi-disciplinary integrated cancer care solutions.

History of Varian Medical Systems:

 * The beginnings of Varian started in the late 1930s when brothers Russell and Sigurd Varian worked on microwave signals to help warn against potential Nazi raids during World War II. They came up with the klystron tube, a high-frequency amplifier that generated microwaves.
 * Varian was officially established in 1948 with brothers Russell and Sigurd Varian and four other scientists. The company incorporated and opened for business with $22,000 of capital and six full-time employees.  A few months later in 1949 Varian announced their first commercial klystron to be used in actual labs.
 * In 1957 Varian came out with the Nobel Vacion pump, the first device of its kind without moving parts or fluids, which made it resistant to power failures. It was also used for simulating conditions in outer space since it was vibration free.
 * In 1959, “a Varian linear accelerator is used for the first time to examine the structural integrity of rocket motors. The first unit was sold to the U.S. Navy to produce radiographs” . Varian was listed on the New York Stock Exchange for the first time on September 14, 1959.
 * In 1960 Varian introduced the Clinac 6 medical linear accelerator (linac). As a result, people realize that linacs can be used to treat cancer which has revolutionized the way cancer was treated and still treated today.
 * In 1976 Varian developed their CT scanner which could take images of the body in only six seconds. Varian eventually sold their CT scanner department to General Electric.
 * The 1990s were a very productive decade for Varian. In 1990 Varian introduced its first multileaf collimator which shapes beams of radiation to match the shape and size of the tumor that is being treated. In 1993 Varian introduces its first software programs that provide hospital workers documentation for the radiotherapy procedures. The program becomes known as VARiS. In 1994 Varian released the Clinac 600SR, a linear accelerator made specifically for radiosurgery. In 1997 The Clinac EX series of accelerators is introduced with integrated multileaf collimators to enable early forms of intensity-modulated radiotherapy (IMRT). This new approach to radiotherapy enables doctors to shape and modulate the radiation beam to sculpt it in three dimensions so that it conforms to the shape of the tumor.
 * In 1997 Varian purchases GE Medical Systems' radiotherapy service and support operation, which covers an installed base of 400-plus medical linear accelerator systems and 340 treatment planning products at hospitals and clinics worldwide.
 * By 1999, Varian Associates had branched into semiconductor, vacuum tube, and medical device fields. On April 2, 1999 these divisions split to become Varian Semiconductor, Varian, Inc. and Varian Medical Systems.In 1999, Varian became officially known as Varian Medical Systems, a world-wide organization manufacturing products for radiotherapy, radiosurgery and X-ray imaging (“Varian Medical”).
 * In 2000, Varian received FDA approval to officially upgrade to VARiS information system which facilitates the management of all patient data.
 * In 2002, Varian moved its Security and Industrial Products operations from Palo Alto, California to Las Vegas, Nevada. Las Vegas is also where Varian holds there training courses for new hires.
 * In 2008, Varian introduced the RapidArc volumetric arc therapy system to speed up the delivery of image-guided radiotherapy.
