TomoTherapy and Vision RT Partner to Expand Hi-Art(R) System Imaging Options

AlignRT(R) 3D Imaging Technology to be Showcased at ASTRO 2008

MADISON, Wis.--(HSMN NewsFeed)--TomoTherapy Incorporated (NASDAQ: TOMO ) announced today that it has partnered with Vision RT to expand imaging options for Hi·Art® treatment system users. The companies will jointly introduce AlignRT® 3D imaging technology for the Hi·Art platform at the annual meeting of the American Society for Therapeutic Radiology and Oncology (ASTRO) in Boston, Mass., Sept. 21-25, 2008. TomoTherapy will distribute AlignRT® for use with both its TomoHelical™ and new TomoDirect™ delivery modes.

“We are excited about our strategic alliance with Vision RT, a company that is as focused on best-in-class clinical workflow and high-quality patient treatments as we are,” said Fred Robertson, CEO of TomoTherapy. “AlignRT® does for Hi·Art system imaging what TomoDirect does for Hi·Art treatment delivery: both provide a new option for our users that can significantly improve patient throughput across a broad range of cancer cases.”

AlignRT® for the Hi·Art platform will consist of two ceiling-mounted 3D camera units, each focused toward the external isocenter of the radiotherapy device. Immediately prior to treatment, the patient will lie on the treatment couch for initial set-up. The cameras will then quickly acquire a surface scan of the body in treatment position, and state-of-the-art software will be used to register real-time image data to the reference surface scan, and—within seconds—provide new couch coordinates for optimal patient positioning.

According to Corey Lawson, director of product strategy for TomoTherapy, the AlignRT® offering complements the Hi·Art system’s integrated CTrue™ imaging technology: “CTrue will continue to be used extensively when the tumor is deep-seated, or can move internally without external evidence. However, we believe AlignRT® will prove useful in approximately 40 percent of cases, based on a standardized mix. Where this technology is best suited, we estimate a 50 percent reduction in setup and registration time.”

“The Hi·Art treatment system offers an innovative approach to radiation therapy,” said Dr. Norman Smith, CEO of Vision RT. “We are delighted to partner with TomoTherapy to expand imaging options while boosting patient throughput for this next-generation platform. In addition, through this partnership, we look forward to developing advanced features that will further enhance the accuracy and precision of TomoTherapy treatments for a broad patient population.”
