July 6, 2010 – Varian Medical Systems and Brainlab recently announced the expansion of their partnership to incorporate Novalis technology and other Novalis Radiosurgery Program elements with the recently launched TrueBeam STx system. The announcement was made at the 5th International Conference of the Novalis Circle, a meeting of Novalis radiosurgery users that provides a platform for collaboration between clinicians to advance the field of radiosurgery.
This expanded agreement is an extension of a relationship between the two companies that began in 1996 and grew with their collaboration around the Novalis Tx radiosurgery platform, which launched in 2007. Novalis Powered by TrueBeam STx will give clinicians radiosurgical and image-guidance capabilities designed for targeted stereotactic radiosurgery (SRS) and stereotactic body radiotherapy (SBRT) treatments. It will include Brainlab iPlan treatment planning and ExacTrac room-based X-ray imaging technology as well as Varian’s HD120 MLC multileaf collimator for high resolution beam shaping.
The TrueBeam STx is specially configured for advanced radiosurgery and is designed to treat a moving target with speed and accuracy. A TrueBeam system can deliver treatments up to 50 percent faster with a dose delivery rate of up to 2,400 monitor units per minute, double the maximum output of earlier Varian systems. This makes it possible to offer greater patient comfort by shortening treatments and to improve precision by leaving less time for tumor motion during dose delivery.
