Varian manufactures a range of megavoltage LINACs with varying levels of features and complexity, for example different numbers of multileaf collimators or the ability to perform radiosurgery.[18]

TrueBeam is a radiotherapy system.[19]

The EDGE radiosurgery suite was launched in 2012.[20] The first cancer centers to use the new system were the Champalimaud Foundation in Lisbon, Portugal and Henry Ford Health System in Detroit, Michigan.[21]

In 2017, Varian launched Halcyon. The system features unique dual-layer MLC that enables high modulation with low leakage for every field or arc.Halcyon is engineered ergonomically to be intuitive, friendly and comfortable for clinical staff and patient alike. This human centered approach means there are fewer parts and protocol for staff to worry about, more time freed up to advance clinical capabilities, and most importantly, more opportunities to provide the highest level of care for every patient.

Varian manufactures the ProBeam Proton Therapy System, with current and planned installations at several sites globally.[23] These are an all pencil-beam scanning proton therapy system utilizing IMTP (intensity modulated proton therapy), which was developed with PSI of Switzerland.[24] Varian also develops medical software and radiology information system for proton treatment planning system.

This new solution is designed to deliver an entire adaptive treatment in a typical 15-minute timeslot, from patient setup through treatment delivery.

In 1999 Varian Medical Systems, Inc. sued a former employee for defamation after they posted numerous messages criticizing the company on the Internet.[25] The lawsuit led to the ruling of Varian v. Delfino by the California Supreme Court on the question of whether a trial could proceed while denial of the defendant's anti-SLAPP motion was under appeal. After the state supreme court ruled that a new trial would be necessary because of that technical concern,[26] the case was settled on undisclosed terms.

On April 25, 2012 a US federal judge in Pittsburgh awarded attorney fees, costs, and doubled damages totaling $73.6 million to the University of Pittsburgh after the university won a suit on medical patent infringement grounds against Varian.[27]
