INVITATION Stockholm, April 5, 2005 Elekta has the pleasure to invite you to visit us at the Annual Meeting of the American Association of Neurological Surgeons (AANS), in New Orleans, Louisiana on Monday 18 April, 2005.

AANS holds a yearly conference and exhibition, which is the most important US event in the neurosurgical field. This 73rd annual meeting takes place on April 18-20, 2005 at the Ernest N. Memorial Convention Center in New Orleans, Louisiana.

Elekta will exhibit its full range of neurosurgical products and systems including Leksell Gamma Knife®, Leksell Stereotactic System® and Elekta Neuromag®.

We will also display Elekta Synergy® S, the new generation radiation oncology system. Developed for stereotactic radiotherapy, Elekta Synergy® S provides fine resolution beam-shaping for challenging extracranial indications and is the ideal complement to Leksell Gamma Knife®.

Representatives from Elekta corporate management will be present in our booth #2409 to answer your questions. There will also be live presentations of our systems and specialists at hand to give you detailed information about our exhibits.
