ELEKTA TO DELIVER LEKSELL GAMMA KNIFE PERFEXION TO CROMWELL HOSPITAL IN LONDON, UK

PRESS RELEASE Stockholm, Sweden, August 2, 2006 Cromwell Hospital will be the first center in the UK to commission Leksell Gamma Knife® Perfexion™, Elekta’s brand new system for stereotactic radiosurgery in the brain, cervical spine and head & neck regions. This top of the line system for non-invasive treatment of tumors and other brain disorders is designed for unlimited cranial reach and has been developed with a strong focus on ease of use and comfort for both patients and staff.

On July 31, 2006, Cromwell Hospital, London's premier independent hospital with over 500 specialists covering more than 70 specialties, confirmed the order to Elekta to install Leksell Gamma Knife Perfexion later this year. “The Gamma Knife Center at Cromwell Hospital has been a success, with over one thousand patients treated since inauguration in 1998, benefiting British and over seas patients”, says Professor Christer Lindquist, MD, PhD, Director of the Gamma Knife Center at Cromwell Hospital and a Gamma Knife pioneer together with Professor Lars Leksell in the 1970’s and 80’s. “Leksell Gamma Knife Perfexion is a quantum leap in dosimetry, ease of use as well as patient and staff comfort. By installing the new Gamma Knife at our center, we will be able to provide more conformal treatment options in less time, automate the record and verify procedure, dramatically improve patient throughput and treat lesions which previously could not be reached”, Professor Lindquist concludes. “At Cromwell Hospital, our aim is to provide the best possible care using the most up-to-date technology available. Our Leksell Gamma Knife unit was the first in London and has over the years been an important tool for our clinicians. It has enabled our patients to choose a non-invasive form of neurosurgery which usually allows them to return to their normal lifestyle the following day. For Cromwell Hospital, being Britain's leading private hospital with the greatest range of technology of any independent hospital in the UK, it was a natural decision to upgrade our standard of care by acquiring Leksell Gamma Knife Perfexion”, says Professor Keith Britton, Chairman of the Board of Directors at Cromwell Hospital. Leksell Gamma Knife Perfexion was introduced to the neurosurgery and radiation oncology communities at the 13th International Leksell Gamma Knife Society Meeting, in Seoul, Korea on May 21-25 and the initial response has been overwhelmingly positive. “We are very pleased to receive the order to supply Professor Lindquist and his colleagues at Cromwell Hospital with the first Leksell Gamma Knife Perfexion in the UK and one of the first in Europe”, says Olof Sandén, Regional Vice President and head of Elekta’s Sales, Marketing & Service in Europe. “The gold standard has gone platinum and this has already created quite a ‘buzz’ around the world and also in Europe, where several current Gamma Knife Centers and prospective customers now are planning on how to accommodate Leksell Gamma Knife Perfexion into their programs in the near future”, ends Olof Sandén. In early July, 2006, the first installation of Leksell Gamma Knife Perfexion was carried out at Hôpital de la Timone (University Hospital La Timone) in Marseille, France and on July 10, clinical treatments commenced with 10 patients successfully treated in the first week of operation. ****** Leksell Gamma Knife® Perfexion™ is subject to regulatory clearance in North America. ****** For further information, please contact: Peter Ejemyr Group VP Corporate Communications, Elekta AB Tel: +46 733 611 000 e-mail: peter.ejemyr@elekta.com About Cromwell Hospital Cromwell Hospital, an internationally recognized Center of Excellence, is Britain's leading private hospital with the greatest range of technology of any independent hospital in the UK.
