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.
