RaySearch Laboratories and TomoTherapy Inc. to show first product concepts at
ASTRO 2007 meeting

RaySearch is developing a suite of products under an agreement with TomoTherapy
Inc that was announced by RaySearch in August 2007. Three products have now been
specified and initial works in progress concepts will be shared at the annual
ASTRO meeting in Los Angeles, October 28th - November 1st. 

“We are very pleased that the development is progressing at full speed and the
fact that we can demonstrate new functionality already is a sign of our
considerable commitment to this collaboration,” says RaySearch's CEO, Johan Löf.

TomoTherapy CEO, Fred Robertson, M.D., sees this collaborative effort between
two industry innovators as one that will benefit clinicians and patients alike.
“RaySearch has a reputation for developing scientifically innovative algorithms
and applying them to software solutions that enhance products and clinical
workflow,” Roberston said. “We are excited to be able to take advantage of their
expertise as we extend the reach of our products and fulfill our mission to
provide better radiation treatment for patients worldwide.”

The suite of software products in development will facilitate transfer of
radiation therapy treatment plans between TomoTherapy® Hi•Art® treatment systems
and conventional linear accelerators, and extend the Hi•Art system's treatment
planning functionality. These developments will lead to improved workflow
coordination, more efficient product utilization and increased patient treatment
capacity. The first product is expected to be released in 2008.
