Still River Systems Announces Operation of the World's Highest Magnetic Field...( LITTLETON Mass. May 21 /- Still R...)

LITTLETON, Mass., May 21 /PRNewswire/ -- Still River Systems announces the successful development and operation of the world's highest magnetic field cyclotron as part of the development of its Monarch250(TM) proton therapy system. This cyclotron is operating at 10 Tesla and conclusively demonstrates that cyclotrons at this high field strength can be designed and optimized for proton radiation therapy. By increasing the operating magnetic field, Still River Systems is developing a cyclotron that weighs less than 20 tons, a 90% reduction over the current generation of proton therapy cyclotrons. "We are excited to report this technical breakthrough," says Kenneth Gall, Ph.D., Chief Technology Officer and Founder of Still River Systems. "While magnets of this strength are already in use in medical applications, the challenge has been to operate a cyclotron at this very large magnetic field."

Conventional proton radiation therapy cyclotrons are based on non-superconducting technology, and operate at low magnetic fields. In 2004, Still River Systems partnered with the Massachusetts Institute of Technology (MIT) to develop this next generation of proton therapy cyclotron using high magnetic field technology currently used in research and Magnetic Resonance Imaging (MRI) applications. "Our goal is to make proton radiation therapy treatment available to hospitals and cancer centers worldwide. This was only possible through a significant reduction in the cost and size of the proton therapy equipment and facility which can be achieved by using high-magnetic field technology," says Marc Buntaine, Chief Executive Officer of Still River Systems.
