BARNES-JEWISH HOSPITAL UPGRADES RADIOSURGERY CAPABILITIES WITH LEKSELL GAMMA
KNIFE® PERFEXION™

PRESS RELEASE	
Stockholm, Sweden, August 14, 2007

The highly respected Barnes-Jewish Hospital has placed an order for Leksell
Gamma Knife® Perfexion™, the most advanced system for non-invasive radiosurgery
in the world.

Leksell Gamma Knife Perfexion is a revolutionary alternative to traditional
open-brain surgery and daily radiation treatments, using focused doses of
radiation without making a single incision to treat malignant and benign brain
tumors, as well as, other brain disorders.

Performing Gamma Knife radiosurgery since 1998, the Gamma Knife center at
Barnes-Jewish Hospital offers stereotactic radiosurgery for patients in the St.
Louis-Metropolitan area, the surrounding Midwest region, as well as, patients
from more distant locations."For more than nine years, the Gamma Knife of St. Louis has provided greater
options in treating patients with brain tumors, as well as, other intracranial
structures,” says Keith M. Rich, M.D., co-director of the Gamma Knife of St.
Louis at Barnes-Jewish Hospital. “We're looking forward to the greater
capabilities the Leksell Gamma Knife Perfexion unit will provide in the near
future."

Gamma Knife surgery has become the world's most widely used radiosurgery
treatment due to its extraordinary accuracy, reduction of excess radiation dose
to the body, extensive history and clinical documentation. Unlike other systems
designed to treat the whole body, Leksell Gamma Knife specifically is designed
to optimize treatment to the head - a fact appreciated by neurosurgeons and
patients alike.

Building a Better Treatment System

Developed in conjunction with leading neurosurgeons, Leksell Gamma Knife
Perfexion is:

• Precise - thousands of radiation beams converge with a level of accuracy more
than 0.5 mm, about the thickness of a strand of hair, leaving nearby healthy
tissue undamaged. 
• Proven - With almost 500,000 patients treated worldwide, and thousands of
peer-reviewed scientific articles, the system has unmatched clinical experience.
• Safe - Unwanted radiation dose to the body is up to 100 times less than that
of competing technologies.
