History

Early Variants began in the late 1930s when Russell's brothers and Sigurd Varians worked on microwave signals to help warn against potential Nazi attacks during World War II. They come with a klystron tube, a high-frequency amplifier that produces microwaves.

The variant was officially established in 1948 with Russell and Sigurd Varian brothers and four other scientists. The company was founded and opened for business with a capital of $ 22,000 and six full-time employees. A few months later in 1949, Varian announced their first commercial klystron for use in the actual laboratory.

In 1957 the Varian came out with the Nobel Vacion pump, the first device of its kind with no moving parts or fluid, which made it resistant to electrical interference. It is also used to simulate conditions in outer space due to vibration free.

In 1959, "Linear linear accelerator was used for the first time to check the structural integrity of a rocket motor.The first unit was sold to the US Navy to produce radiographs". The variant was listed on the New York Stock Exchange for the first time on September 14, 1959.

In 1960, Varian introduced the Clinac 6 line linear line accelerator (linac). As a result, people are aware that linac can be used to treat cancers that have revolutionized the way cancer treatments are and are still being treated to this day.

In 1976 Variant developed its CT scanner that can take body pictures in just six seconds. Variants eventually sell their CT scanner department to General Electric.

The 1990s were a very productive decade for Variants. In 1990, Varian introduced the first multileaf collimator that formed a radiation beam to adjust the shape and size of the tumor being treated. In 1993, Varian introduced the first software program that provides documentation of hospital workers for radiotherapy procedures. This program is known as VARiS. In 1994 Variant released the Clinac 600SR, a linear accelerator made specifically for radiosurgery. In 1997, the Accelerac EX series was introduced with an integrated multileaf colarator to enable radiotherapy radiation (IMRT) early forms. This new approach to radiotherapy enables doctors to form and modulate radiation rays to sculpt them in three dimensions to fit the shape of the tumor.

In 1997, Varian purchased GE radiotherapy services and surgical support, which included a 400 base of installed medical linear accelerators and 340 care planning products at hospitals and clinics around the world.

In 1999, Varian Associates has branched out into semiconductors, vacuum tubes, and medical equipment fields. On April 2, 1999 this division was divided into Varian Semiconductor, Varian, Inc. and Varian Medical Systems. In 1999, Varian was officially known as Varian Medical Systems, a worldwide organization that produces products for radiotherapy, radiosurgery and X-ray imaging.

In 2000, Varian received FDA approval to formally upgrade to a VARiS information system that facilitates the management of all patient data.

In 2002, Varian transferred its Security and Industrial Products operations from Palo Alto, California to Las Vegas, Nevada. Las Vegas also places Variants organizing training courses for new hires.

In 2008, Varian introduced RapidArc volumetric arc therapy system to speed up the delivery of image guiding radiotherapy.

Acquired company

Varian Medical Systems has acquired other companies including Pan-Pacific Companies, ACCEL Instruments, Bio-Imaging Research, Inc. Sigma Micro Informatique Conseil, Argus Software, Velocity Medical Solutions. and MeVis Medical Solutions AG

In January 2018, the company announced the acquisition of Sirtex Medical worth $ 1.3 billion.

In February 2018, Varian Medical Systems announced that they are buying a Canadian-based private company called Evinance Innovation that specializes in clinical decision support software. Innovation Evinance will further assist Oncology 360 Varian's maintenance management platform by integrating scientific workflows and decision support. With patients and physicians this integration can make better planned decisions for future care. This acquisition is the latest step in Varian's long-term strategy to become a global leader in multi-disciplinary integrated cancer treatment solutions.

Spin-off company

30.01.2017 spin-off from Varex Imaging Corporation (manufacture of X-ray imaging products) from Varian Medical Systems has been successfully completed.

Products

Variants offer various types of advanced radiation treatment systems that provide special care and patient care. The Variant system can be easily modified and upgraded depending on clinical needs.

X-ray

Variants produce various LINAC megavoltages with varying levels of features and complexity, such as the number of different multileaf collantators or the ability to conduct radiosurgery.

Halcyon System

The latest Variant cancer care machine, designed to simplify and guide radiotherapy with radiation intensity guided by better images. Can be used in standard safes but also in smaller and lightly shielded rooms.

Radiosurgery Edge System

The radiosurgery system of Edge revolutionized the way advanced radiosurgery was delivered. Capable of both photon and electron energy. Can treat various types of cancer including the lungs, brain and spine. The EDGE radiosurgery series was launched in 2012. The first cancer centers using the new system were the Champalimaud Foundation in Lisbon, Portugal and the Henry Ford Health System in Detroit, Michigan.

TrueBeam Radiotherapy System

TrueBeam platform system is a fully integrated system for radiotherapy and radioseluler image guides. Allows for customization of energy and additional capabilities.

VitalBeam Radiotherapy System

The VitalBeam Maestro control system synchronizes a monitoring system that handles sophisticated cases accurately. Using x-ray technology to treat all parts and organs of the body.

Clinical iX System

The high-performance Clinac system is a reliable accelerator designed to provide a wide range of image and patient care options. Built on analog and digital platforms.

Proton therapy

The variant manufactures the ProBeam Proton Therapy System, with current and planned installations on several sites globally. These are all ray beam proton therapeutic systems that utilize IMTP (proton intensity modulation therapy), developed with Swiss PSI. The variant also developed medical software and radiology information systems for proton treatment planning systems.

Litigation

Free speech

In 1999, Varian Medical Systems, Inc. sued a former employee for defamation in Varian v. Delfino. The employee stopped. Michelangelo Delfino posted many messages criticizing the company on the Internet. The case was finally settled with an undisclosed requirement. The lawsuit itself is controversial, massively publicized, and leads to important decisions on California anti-SLAPP legislation. Some rights-based labor rights activists upheld Delfino as an example because he mortgaged his home to pay his legal bills associated with a lawsuit with Varian.

University of Pittsburgh

On April 25, 2012, a US federal judge in Pittsburgh awarded $ 73.6 million in lawyers, fees and damages to the University of Pittsburgh after the university won a lawsuit on the basis of a medical patent infringement on the Varian.
