PRESS RELEASE Stockholm, April 7, 2006 To further complement the Elekta portfolio of stereotactic neurosurgery and radiation therapy solutions, an agreement with 3D Line Medical Systems allows Elekta to increase the range of stereotactic products offered to customers, including the 3D Line ERGO++ treatment planning system.

Elekta, a world leader in radiation oncology and non-invasive neurosurgery solutions, has this week signed a global marketing agreement with 3D Line Medical Systems, srl. The agreement allows Elekta to offer a complete stereotactic radiosurgery palette, including 3D Line’s stereotactic cones and ERGO treatment planning system with all new Elekta digital accelerators. This agreement immediately enhances the stereotactic delivery products from Elekta, in particular by providing stereotactic planning opportunities for the Beam Modulator™.

The ERGO treatment planning system has a modular design that supports planning for classical stereotaxy, using circular (cylindrical) cones (collimators) in single and multi-fraction treatment delivery. The open systems philosophy of both companies means that virtually all commercial head and body frames are supported for stereotactic localization, including Leksell® Coordinate Frame G, Elekta Esarte™ Frame and Medical Intelligence localizers.

The ERGO planning system will be demonstrated on the Elekta booth at the 2006 American Association of Neurological Surgeons (AANS) meeting in San Francisco, April 23-27, providing planning support for the Elekta stereotactic head and body frame systems.

“With Elekta we have found a group of highly experienced people, sharing with us the passion to turn everyday clinical challenges into real solutions by combining research and innovation. Elekta and 3D Line have been working to export the classical stereotactic accuracy to any anatomical region. This partnership agreement combines the power of high performance imaging with superior stereotactic planning capabilities, to give rise to a new evolution of modern radiotherapy,” says 3D Line Medical Systems CEO, Roberto Pellegrini.

Elekta Product Manager for IMRT and Treatment Planning, Nick Linton, added, “We have had an informal relationship with 3D Line for several years and have provided products and services to mutual customers in the field of radiation therapy planning. This agreement continues a successful relationship and expands the choice of options for those customers looking at stereotactic solutions, image guided radiation therapy and radiosurgery.”

“We are very pleased to be able to offer 3D Line stereotactic planning and circular cones to enhance and support our stereotactic product offering across the range of Elekta Digital Accelerators. We expect that this will be a very beneficial relationship for our customers,” concluded Sarah Edwards, Elekta Product Manager for Stereotactic Radiation Therapy.
