First Patient treated with RayStation® in China

RaySearch Laboratories AB announces that the first patient in China has been
treated with a treatment plan created with RaySearch’s treatment planning system
RayStation®.

The treatment was carried out at the First Hospital of China Medical University
in Liaoning, China. The patient was treated for nasopharynx cancer using
intensity-modulated radiation therapy (IMRT) and the treatment was delivered by
an Elekta Synergy linear accelerator.

“RayStation® is a fast and efficient treatment planning system. The interface of
RayStation® is intuitive and straightforward, which makes the system very user
-friendly. It has a range of tools that allows us to fully leverage the 4D data
we generate with our CT-on-rails to perform deformable registration and dose
tracking in a highly efficient manner. We also use the tool for multi-criteria
optimization to reduce the dose to the surrounding organs at risk and protect
the patient better”, says Xia Bin, Chief Medical Physicist of The First Hospital
of China Medical University.

“We received regulatory approval for RayStation® on the Chinese market in July
and it is very pleasing that the system has already been used to treat patients.
China represents a large growth opportunity for RaySearch and we have already
received several orders so we are off to a very good start together with our
distributor Kang Li Da”, says Johan Löf, CEO of RaySearch.”
