RaySearch Laboratories AB (publ.) announces that the Radiation Therapy
Department at Columbia University Hospital recently has added several
RayStation® licenses and the required hardware to support a distributed network
environment and adaptive radiation therapy on their Varian and Siemens linear
accelerators.

The combined technologies of deformable registration, dose accumulation and
adaptive therapy are now available to the planning team which will allow them to
commence using advanced planning solutions that focus on treating cancer in a
more dynamic way.

Hansen Chen, Director of Technology Development and Systems Integration will be
working towards an early 2014 implementation of adaptive therapy, using
RayStation® to examine the progress of prescribed treatments over time,
correcting delivery as needed to assure that the treatment as originally planned
is successfully completed. Hansen Chen comments: “We need efficient tools like
RayStation® to help us with the clinical workflow when it comes to technologies
like adaptive therapy. To actually apply this type of treatment monitoring and
correction takes a great deal of effort and resource planning. If done
correctly, we can improve patient care without losing efficiency or increasing
costs.”

“We are looking forward to working with Hansen and his organization in advancing
these technologies. It is important for us to have customers who want to apply
the most advanced planning techniques in their clinics. This helps everyone
because their input and practical application helps us make our solutions even
better”, says Marc Mlyn, President of RaySearch Americas.

Johan Löf, CEO of RaySearch, adds: “We see adaptive therapy as the next big step
in radiation therapy and have worked very hard for several years to create a
state-of the-art treatment planning solution with full support for adaptive
therapy. The clinical implementation at Columbia is an important step in the
development of this new field that will grow in importance immensely over the
next few years.”
