About RaySearch 
RaySearch's business concept is to provide innovative software to radiation
therapy clinics for more effective radiation treatment of cancer. RaySearch, a
spin-off from Karolinska Institutet, was formed in 2000. Through a licensing
agreement with Philips, the company's first product, p-RayOptimizer, has to date
been sold to approximately 1,000 hospitals internationally and more than 100,000
patients have received improved radiation therapy. A licensing agreement was
signed with Nucletron at the beginning of 2004 and deliveries of the first
product based on this partnership, n-RayOptimizer, began in April 2005. In
February 2006 an agreement was signed with Scanditronix-Wellhöfer regarding
development of products for improved quality assurance of IMRT. In October 2006,
RaySearch signed an agreement with Philips covering the development of products
in adaptive radiation therapy. In November 2006 RaySearch signed a development
and license agreement with Nucletron regarding treatment planning for proton
therapy in cancer treatment.

Care sector. RaySearch is based in Stockholm and currently has 29 employees.
