TomoTherapy and NELCO Partner to Reduce Radiation Therapy Construction Costs

MADISON, WI–(Marketwire – November 23, 2010) – TomoTherapy Incorporated (NASDAQ: TOMO), maker of advanced radiation therapy solutions for the treatment of cancer and other diseases, today announced availability of a shielding solution that enables hospitals and cancer centers to quickly, easily and inexpensively build out treatment vaults that are properly shielded for use of the TomoTherapy^® radiation therapy system. The Total Shield^™ by NELCO, the worldwide leader in designing, manufacturing, and installing specialized products and services for the medical, industrial, and construction fields, is a customized shielding enclosure designed to fit around a TomoTherapy unit, making it possible for the radiation therapy system to be placed into existing under-shielded vaults or other treatment rooms where there may not be enough space to install necessary shielding using the existing infrastructure.

Total Shield provides hospitals and cancer centers with the flexibility to put the TomoTherapy system in an existing space, which may be too small or may not include enough shielding for modern intensity-modulated radiation therapy (IMRT) devices. Instead of adding shielding in the walls, the Total Shield enclosure is designed to wrap around the TomoTherapy system itself.

By taking this approach, TomoTherapy customers can potentially save hundreds of thousands of dollars in shielding costs and eliminate the months it takes to install conventional shielding solutions. Total Shield can be installed in just a matter of days. Additionally, because the Total Shield can be easily removed, it can be reused if the TomoTherapy system is eventually moved to a new location.

“Total Shield is the most recent example of how the TomoTherapy system’s unique design, and its small footprint, can allow hospitals and cancer centers to easily adopt cutting-edge cancer care technology in places where other solutions are not feasible,” said Harry Freeman, director of commercial operations at TomoTherapy. “Combined with the TomoTherapy system’s integrated beam stop technology, Total Shield can dramatically reduce the cost of building out a vault with extensive shielding, and enables facilities to get their TomoTherapy system up and running much quicker than other radiation treatment solutions.”

Total Shield was designed collaboratively by NELCO and will be on display in the TomoTherapy booth (#6406) at RSNA 2010, November 28 – December 3, at McCormick Place in Chicago, Illinois.
