Varian Medical Systems, Inc. (Varian Medical) has been awarded order for four new radiotherapy treatment machines from Barts and The London NHS Trust (London's Barts). The new machines are ordered in June 2009 and are equipped with On-Board Imager devices and RapidArc capability.

The new machines will replace three older devices and will be joined by a two-year-old accelerator that is being transferred from the current site and upgraded with RapidArc, giving the hospital five modern Varian linear accelerators when installed.

The new equipment is part of a long-term, multi-million pound managed equipment service contract with Varian Medical both for this initial equipment supply, comprehensive maintenance and ongoing replacement of the radiotherapy equipment at the new Barts and The Royal London hospitals.
