The products are specially developed to optimize radiation therapy and the purpose is to adapt the radiation dose to the shape of the tumor, which allows high doses to be delivered to the tumor while minimizing the dose to surrounding healthy tissue. RaySearch, a spin-off from Karolinska Institute, was formed in 2000. RaySearch has sold its product RayOptimizer to more than 800 hospitals around the world through a licensing agreement with Philips, enabling more than a hundred thousand patients to receive improved radiation therapy. RaySearch was listed on the Stockholm Stock Exchange O-List in November 2003. As of July 1, 2005, RaySearch is listed on the Attract40 segment of the O-List of the Stockholm Stock Exchange. Sales of the products RayBiology and RayMachine began in 2004. The partnership with Philips continues and RaySearch signed a licensing agreement with Nucletron at the beginning of 2004. The latter agreement made Research’s products available to a large number of new clinics worldwide and, consequently, increased the number of potential end customers sharply. Delivery to clinics of OM-Optimizer, the first product based on the partnership with Nucletron, began in April 2005. In May 2005, RaySearch signed a letter of intent with Philips for development of products within adaptive radiotherapy. RaySearch is based in Stockholm and currently has 28 employees.
