Varian RapidArc Technology Used with Novalis Tx System for First Time Outside U.S. to Treat Head and Neck Cancer Patient
BERN, Switzerland, April 21 (Healthcare Sales & Marketing Network) -- A 51-year old female cancer patient from Switzerland has become the first patient outside the U.S. to be treated with RapidArc(TM) radiotherapy technology from Varian Medical Systems (NYSE: VAR ) on a Novalis Tx(TM) platform for radiosurgery and radiotherapy.Rather than targeting tumors with radiation beams from fixed angles, the Novalis Tx unit with RapidArc capability rotates continuously around the patient performing radiotherapy or radiosurgery several times faster than is possible with conventional techniques.
"Our first case was particularly challenging due to the fact that two distinct tumor regions were to be treated using different dose prescriptions," said Professor Aebersold. "The treatment was very quick and we were very impressed by the excellent conformity and good sparing of organs at risk compared to standard IMRT."
"By delivering advanced RapidArc treatments on a gold standard platform such as a Novalis Tx, we were able to combine speed with extremely high precision, to minimize the possibility of movement during treatment, which is particularly important bearing in mind the larger doses we are using."
In summer 2008, Inselspital became the first hospital outside the U.S. to install a Novalis Tx and treatments began in the autumn. Professor Aebersold and his team now plan to explore further stereotactic radiosurgery and stereotactic body radiotherapy treatments, along with hypo-fractionation for fewer treatment sessions as well as techniques and treatments such as partial breast irradiation and frameless treatment of arteriovenous malformations.
Novalis Tx features very high dose delivery rates, which contributes to shorter treatment times. It also offers dynamic fine beam shaping and non-invasive, precise frameless patient positioning for rapid and more comfortable treatments, and allows multiple beam energies of up to 18 million volts for treating deep-seated tumors.
The Novalis Tx platform includes an On-Board Imager(TM) device for pinpointing the tumor and positioning the patient with millimeter precision. The platform's ExacTrac* room-based image-guidance system provides continual imaging during treatment to detect movement and support robotic adjustments in patient positioning. This enhances protection of surrounding healthy tissues while enabling clinicians to concentrate higher, more effective doses on tumors.
