In arc therapy, a linear accelerator gantry moves in a continuous arc around the target while delivering radiation dose. Patients have been routinely treated with this technology since the 1980s, when it was put into use for stereotactic radiosurgery (SRS) of the brain. The advantage was that the low-dose region was spread out over a larger amount of healthy brain, reducing treatment toxicity.

Intensity modulated radiation therapy (IMRT) emerged as a new way to treat patients in the late 1990s and garnered attention because it offered the possibility to avoid radiating healthy tissue with more accuracy than conventional radiation therapy techniques. As a highly conformal 3-D therapy, its precise targeting of a tumor allows higher radiation doses to be delivered more safely.

December 28, 2011 — Clinicians at one of New Zealand's leading hospitals have delivered more than 300 radiotherapy treatments using a newly installed TrueBeam device, from Varian Medical Systems, in the first month of its implementation. The system adds to Wellington Hospital's radiotherapy capabilities and enables fast, precise and efficient treatments.

December 21, 2011 — Varian Medical Systems is introducing a new line of PaxPower X-ray tubes that offer the heat management capabilities of conventional X-ray tubes in a much smaller and lighter package. The tubes are designed to be paired with the company's PaxScan digital detectors for filmless imaging. They will be debuted in Varian's exhibit at the annual meeting of the Radiological Society of North America (RSNA) in Chicago, Nov 27 – Dec. 1. The company will also display its technologies for treating cancer with targeted radiotherapy and radiosurgery.

December 8, 2011 – Clinac and Trilogy medical linear accelerators from Varian Medical Systems, machines that are used to treat cancer with targeted radiotherapy, have been updated to deliver higher doses up to two times faster than was previously possible. They can now also better facilitate treating breast cancer patients on their stomachs (in the prone position) rather than their backs—an approach that can reduce the volume of lung and heart tissue exposed to radiation during treatment.

Stereotactic body radiation therapy (SBRT) is an investigational radiotherapy modality for the treatment of localized prostate cancer. Conventional radiotherapy options include prolonged schedules of daily treatment using relatively low radiation doses over a period of six to nine weeks. SBRT offers promise of an expedient, well-tolerated and effective schedule of only five treatments of larger doses for selected patients for whom current conventional treatment options would be either medically contraindicated or refused by the patient for reasons of inconvenience.

November 23, 2011 – The University of Alabama at Birmingham (UAB) Health System became the first medical center in the world last week to utilize intrafraction motion review (IMR), or "triggered imaging," to continually monitor tumor location during radiosurgery for lung cancer. IMR, which is a unique capability of the TrueBeam linear accelerator from Varian Medical Systems enables visual verification that a tumor is being properly targeted.
