Massachusetts General Hospital in Boston chooses RaySearch's treatment
planning system RayStation®

Massachusetts General Hospital (MGH) in Boston, USA, has selected
RaySearch's treatment planning system RayStation® as their next
generation planning software for delivery of IMRT and VMAT treatments.

In 2008, RaySearch and MGH entered into a long-term research and
development collaboration within the field of multi-criteria
optimization for radiation therapy. In all radiation treatments, the
clinician has to balance conflicting objectives such as obtaining a
sufficiently high target dose to achieve tumor control, while ensuring
that the dose to the surrounding healthy tissues is sufficiently low to
minimize the risk for side effects. Multi-criteria optimization provides
a tool for dealing with these tradeoffs in a stringent fashion. This has
the potential to speed up the time-consuming treatment planning
optimization process where currently the parameters of a treatment plan
are changed through trial and error until a satisfactory plan is found.

The cooperation has resulted in a software product that enables
clinicians to explore and evaluate a representative set of treatment
alternatives in a highly intuitive and efficient way. The solution is
now integrated in RaySearch's proprietary RayStation® treatment planning
system. The new agreement means that MGH licenses RayStation® for
treatment planning of advanced IMRT and VMAT treatments and brings the
solution for multi-criteria optimization into clinical practice for the
first time.

RayStation® integrates all RaySearch's advanced treatment planning
solutions into one flexible system. In addition to the unique
multi-criteria optimization tools, it also includes functionality such
as RaySearch's market-leading algorithms for IMRT and VMAT optimization,
highly accurate dose engines for both photon and proton therapy and has
full support for 4D adaptive radiation therapy. The system is built on
the latest software architecture and has a graphical user interface
offering state-of-the-art usability.

“MGH is one of the most renowned clinics in the United States and we are
of course honored that they have selected RayStation® as their new
treatment planning system. Our research collaboration has been very
successful and I look forward to continuing our partnership in a
clinical setting,” says Johan Löf, CEO of RaySearch.

“The order will generate revenues for the fourth calendar quarter but
has no impact on the financial results for the third quarter that will
be presented on November 12th. The third quarter is generally the
weakest during the year due to seasonal effects and 2010 is no
exception. However, delivering RayStation® to such an advanced and
prestigious clinic as MGH, is a very important strategic milestone that
will have long-term positive effects for RaySearch,” concludes Johan
Löf.

RaySearch will participate as an exhibitor at the annual ASTRO radiation
therapy meeting, which this year will be held in San Diego, October 31
to November 4, and will demonstrate RayStation® in booth 2228.
