First RayStation® order in Scandinavia

RaySearch Laboratories AB has received an order for its RayStation® treatment
planning system from Oslo University Hospital in Oslo, Norway.

Oslo University Hospital is a highly specialized public hospital for citizens of
the South-Eastern Health Region of Norway including Oslo. The hospital also has
a nationwide responsibility for a number of national and multi-regional
assignments. It is a Comprehensive Cancer Center including an institute of
Cancer Research and a Cancer Registry, and has several national centers of
competence. The hospital is Scandinavia’s largest, carrying out more than 1.2
million patient treatments annually, and is responsible for approximately 50
percent of all medical and healthcare research conducted at Norwegian hospitals.
RayStation® will be used at the hospital’s unit for radiation therapy at the
Norwegian Radium Hospital which is one of the largest radiation therapy centers
in Northern Europe.

The hospital will primarily use RayStation® to perform adaptive radiation
therapy. This is an advanced form of radiation therapy where the delivered dose
is adjusted continuously during the course of treatment to account for changes
occurring in the patient’s anatomy. This has a significant potential to increase
the tumor control probability and at the same time reduce the risk for side
effects by sparing healthy tissue. The clinic will also use RayStation® to
perform treatment planning of IMRT treatments and rotational mARC treatments
that are carried out with Artiste linear accelerators from Siemens.

“We are really looking forward to start implementing adaptive radiation therapy
to further improve the precision in our radiation treatments. This requires very
sophisticated software tools and RayStation® really stands out as the best
treatment planning solution on the market for adaptive therapy. I see this as a
starting point of a deep collaboration with RaySearch for both clinical and
research applications”, says Dr. Karsten Eilertsen, Head of Radiotherapy
Physics.

“We have previously sold RayStation® to clinics all over the world but being a
Scandinavian company it is of course an important milestone for us to get our
first RayStation® customer in our home region. Oslo University Hospital is an
excellent clinic with extensive research programs in areas where we are highly
active so I am fully convinced that this will be a very fruitful partnership”,
says Johan Löf, CEO of RaySearch.
