First RayStation order from Australia

RaySearch Laboratories AB has received an order for its RayStation® treatment
planning system from The Radiation Oncology Institute in New South Wales,
Australia.
The Radiation Oncology Institute (ROI) runs two radiation therapy centers in
Wahroonga and Gosford in New South Wales. Radiation Oncology Institute -
Wahroonga is located in the Sydney region. Situated in the grounds of the Sydney
Adventist Hospital, Radiation Oncology Institute - Wahroonga is a private
medical specialist practice originally founded in 1936. Since then the practice
has grown and in 1976 commenced in its current site as the second practice in
New South Wales to be located outside of a Public Hospital. The Gosford centre
was opened for its first patients in August 1995 to service the patients of the
Central Coast who had been travelling to Sydney for treatment. Today Radiation
Oncology Institute - Gosford remains the only radiation therapy facility on the
Central Coast and treats more than 500 new patients every year.

ROI will use RayStation® as its treatment planning system for conventional 3D
-CRT treatments, as well as more advanced treatments, such as IMRT and VMAT. The
order also includes advanced tools enabling a more efficient treatment planning
process, such as Multi-Criteria Optimization. This highly intuitive tool lets
the clinician evaluate the impact of changing different treatment priorities in
real-time, which has a large potential to speed up the time-consuming treatment
planning optimization process. In addition the order also includes fully
integrated tools for deformable registration, dose accumulation and adaptive
radiotherapy. RayStation® will then allow the center to use advanced techniques
to assess the need for re-planning based on accumulated delivered dose using
special adaptive techniques to adjust for anatomical changes occurring during
the course of treatment. If re-planning is needed, RayStation® will allow the
clinicians seamlessly re-optimize the plan based on dose that has already been
delivered.

“ROI selected RayStation® because of its class leading features that will allow
us to provide the most advanced treatment planning techniques including the
ability to provide patient based optimal solutions utilizing RayStation’s unique
adaptive treatment planning and dose tracking features combined with Multi
-Criteria Optimization. We are excited to be the first in Australia to use
Raystation® and look forward to a long and successful association”, says Susan
Mainey, CEO of Radiation Oncology Institute.

Johan Löf, CEO of RaySearch Laboratories adds: “We see a lot of interest for
RayStation® in the Australasian region so we are very happy to announce this
first order in Australia. The Radiation Oncology Institute runs two great
treatment centers and we are of course delighted that they have selected
RayStation® as their treatment planning system for the future.”
