Varian Medical Systems is an American radiation oncology treatments and software maker based in Palo Alto, California. Their medical devices include linear accelerators (LINACs) and software for treating cancer and other medical conditions with radiotherapy , radiosurgery , proton therapy , and brachytherapy .
Varian Associates was one of the first high-tech companies in Silicon Valley.It was founded in 1948 by Russell H. and Sigurd F. Varian, William Webster Hansen, and Edward Ginzton to sell the klystron, the first vacuum tube which could amplify electromagnetic waves at microwave frequencies, and other electromagnetic equipment.
The Varians went on to found Varian Associates to commercialize the technology (for example, to make small linear accelerators to generate photons for external beam radiation therapy). Their work was preceded by the description of velocity modulation by A. Arsenjewa-Heil and Oskar Heil (wife and husband) in 1935, though the Varians were ...
Russell and Sigurd founded Varian Associates in 1948, along with Hansen and Ginzton. They initially created the company to commercialize the klystron [2] and develop other technologies, such as small linear accelerators to generate photons for external-beam radiation therapy. They also were interested in nuclear magnetic resonance technology.
As linear accelerators were developed with higher beam currents, using magnetic fields to focus proton and heavy ion beams presented difficulties for the initial stages of the accelerator. Because the magnetic force is dependent on the particle velocity, it was desirable to create a type of accelerator which could simultaneously accelerate and ...
Varian TrueBeam Linear Accelerator, used for delivering IMRT Intensity-modulated radiation therapy (IMRT) is an advanced type of high-precision radiation that is the next generation of 3DCRT. [ 76 ] IMRT also improves the ability to conform the treatment volume to concave tumor shapes, [ 10 ] for example when the tumor is wrapped around a ...
