History
RaySearch was established in 2000 as a spin-off from Karolinska Institutet in Stockholm. Founder and CEO Johan Löf started the company based on knowledge acquired during his PhD work on radiation treatment of moving tumors at Karolinska Institutet in Stockholm, Sweden. A few months after its establishment, RaySearch entered into a partnership agreement with Philips Medical Systems, which resulted in the development of the P3 IMRT module of the Pinnacle treatment planning system in 2001.

In 2003, RaySearch was listed on the O-list of the Stockholm Stock Exchange, which has been part of Nasdaq since 2008. Between 2004 and 2007, RaySearch entered into partnership agreements with Nucletron, IBA Dosimetry, TomoTherapy, and Varian Medical Systems. RaySearch algorithms were adopted for use in several of the leading radiation therapy treatment planning systems.

RaySearch also began engaging in clinical research collaborations, notably working with Princess Margaret Hospital, and Massachusetts General Hospital, to pioneer adaptive therapy and multi-criteria optimization.

In 2008, RaySearch made the decision to develop and market its own treatment planning system. The RayStation system was launched in 2009, and West German Proton Therapy Center Essen placed the first order in the same year.

RayStation received US FDA 510(k) clearance in 2010 and Massachusetts General Hospital subsequently placed the first US order for the system. The first patient treatment with RayStation took place in 2011 at Massachusetts General Hospital.

The first complete version of RayStation was released in 2012, and RayStation was approved for sale in China in 2013.
