TomoTherapy Releases Hi-Art(R) Treatment System Version 3.1

Update Expected to Increase Patient Throughput for Advanced Radiation Therapy

MADSION, Wis.--(HSMN NewsFeed)--TomoTherapy Incorporated (NASDAQ:TOMO ) announced today that it has begun shipping a faster version of its proven platform for image-guided, intensity-modulated radiation therapy (IG-IMRT). Version 3.1 of the TomoTherapy® Hi-Art® treatment system includes new software and hardware features that enhance clinical productivity and system usability, and are expected to increase patient throughput.

During December, TomoTherapy conducted a time-on-task study to assess the Hi-Art System version 3.1 enhancements in a clinical setting. Results show savings of up to 5 minutes per patient have been achieved over previous versions, based on a standard 20-minute treatment slot.

“We couldn’t be happier with the changes TomoTherapy has made,” said Dr. Lane Rosen, director of radiation oncology at the Shreveport, La.-based Willis-Knighton Cancer Center, a version 3.1 pilot site. “We were previously treating 20 to 25 patients a day with the Hi-Art System. Now, we can treat as many as 30 patients a day, with no compromise in the quality we’ve come to expect from this revolutionary technology.”

Said Fred Robertson, CEO of TomoTherapy: “We are very pleased to make Hi-Art 3.1 available to the radiation oncology community. This release demonstates that a cancer center doesn’t have to choose between reducing treatment times and delivering superior radiation therapy. The TomoTherapy Hi-Art treatment system empowers clinics to do both, with confidence.”

Software highlights of Hi-Art version 3.1 include a variety of delivery system design improvements that eliminate delays in the treatment process. Hardware updates include the addition of a second planning workstation to facilitate parallel clinical workflow, and the introduction of the new High Performance Couch, which provides efficiencies in the quality assurance, imaging and treatment processes.

All Hi-Art System orders shipped beginning Jan. 2, 2008 include the software and hardware features of version 3.1. Existing TomoTherapy customers will receive the software upgrade free of charge.
