History

RaySearch was established in 2000 as a spin-off from Karolinska Institutet in Stockholm. ^[3] 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. ^[4] 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. ^[5]

In 2003, RaySearch was listed on the O-list of the Stockholm Stock Exchange, ^[6] which has been part of Nasdaq since 2008. ^[7] Between 2004 and 2007, RaySearch entered into partnership agreements with Nucletron, ^[8] IBA Dosimetry, ^[9] TomoTherapy, ^[10] and Varian Medical Systems. ^[11] 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, ^[12] and Massachusetts General Hospital, ^[13] to pioneer adaptive therapy and multi-criteria optimization.

In 2008, RaySearch made the decision to develop and market its own treatment planning system. ^[14] The RayStation system was launched in 2009, and West German Proton Therapy Center Essen placed the first order in the same year. ^[15]

RayStation received US FDA 510(k) clearance in 2010 ^[16] and Massachusetts General Hospital subsequently placed the first US order for the system. ^[17] The first patient treatment with RayStation took place in 2011 at Massachusetts General Hospital. ^[18]

The first complete version of RayStation was released in 2012, ^[19] and RayStation was approved for sale in China in 2013. ^[20]
