RayStation® will be extended to include treatment planning for the TomoTherapy® and CyberKnife® Systems

RaySearch Laboratories AB (publ) (NASDAQ OMX Stockholm: RAY B) and Accuray
Incorporated (Nasdaq: ARAY) announced today that they have expanded on their
existing relationship with the signing of a new long-term collaboration
agreement, which will lead to the integration of treatment planning support for
the TomoTherapy® and CyberKnife® Systems in the RayStation® treatment planning
system (TPS). RayStation is one of the most advanced independent treatment
planning systems available and will provide an ideal complement to the unique
Accuray treatment delivery systems, enabling customers to choose the delivery
technology that will best meet their needs. Accuray and RaySearch previously
announced a long-term collaboration regarding the RayCare® oncology information
system.
“This agreement marks an important progression in our partnership with
RaySearch. We believe the integration of their industry-leading TPS along with
our innovative treatment delivery systems will enable clinicians to further
optimize their experience and use of Accuray technology long-term,” said Joshua
H. Levine, president and chief executive officer of Accuray. “Our goal is to
maximize the clinical effectiveness of our Systems and enhance the ease with
which they integrate within the radiation oncology department. We are pursuing
multiple paths to achieve this result, including this agreement with RaySearch,
which will provide both flexibility and enhanced options for our customers.”

Under the contract, Accuray will have the opportunity to offer RayStation to
clinicians who use the TomoTherapy and CyberKnife System product portfolios.
Current RayStation users report that the software provides multiple benefits
including advanced treatment planning tools, leading workflow support and an
excellent user experience, all of which enhance treatment delivery flexibility
within a radiation oncology department.

Accuray has an installed base of more than 500 TomoTherapy Systems and more than
300 CyberKnife Systems worldwide. Treatment planning support for TomoTherapy
Systems in RayStation is targeted for release during 2016 and support for
CyberKnife Systems for release during 2017.

“This agreement with Accuray enables us to expand our relationship with a like
-minded company committed to improving the way radiation therapy is delivered,”
said Johan Löf, president and chief executive officer of RaySearch Laboratories
AB (publ). “For the first time ever, treatment planning for both of the Accuray
systems as well as conventional linear accelerators will be available in one
integrated treatment planning system. This integration alone will entail
significant gains in efficiency for clinics that have several machine types.
Additionally, we see that many of RayStation’s unique strengths are
exceptionally well suited to the Accuray systems. In summary, we think that this
collaboration will strengthen both RayStation’s and the Accuray systems’
competitiveness.”
