Siemens Healthcare Announces Exclusive Partnership With Prowess Inc.

Concord, California (ots/PRNewswire) -

- Plans to Integrate Treatment Planning System with Oncology
Solutions Technology

Siemens Healthcare (www.usa.siemens.com/healthcare) announces an
exclusive partnership with Prowess Inc. to develop advanced radiation
oncology treatment planning software for integration into Siemens'
linear accelerators. The combination of Prowess' unique treatment
planning system with Siemens' leading oncology solutions technology
will help provide users with one of the most effective and reliable
radiation therapy treatment solutions available in the market.

This agreement authorizes Siemens Healthcare to share the basic
intellectual property of Prowess' patented Direct Aperture
Optimization (DAO) planning software, allowing Siemens to incorporate
Prowess' software into the treatment planning tools for its linear
accelerators. This, in turn, will help users to dramatically reduce
the number of segments, monitor units, and overall treatment times.

"This partnership with Prowess will provide us the ability to
deliver a solution that helps clinical teams treat patients more
efficiently by reducing treatment times, dosage, and exposure of
healthy tissues," said Holger Schmidt, Chief Executive Officer,
Siemens Healthcare, Oncology Care Systems. "The open system
architecture will enable Siemens to offer users one of the broadest
selections of treatment planning tools on the market."

"Working closely with Siemens, we are developing a joint solution
that combines Siemens' innovative oncology therapy solutions with our
market-leading treatment planning system," said John Nguyen, CEO of
Prowess. "We look forward to realizing the full potential of this
partnership and continuing to drive innovation in the oncology
field."

The Prowess DAO-based Plan-to-Patient tool(i) for Adaptive
Radiation Therapy (ART) has been clinically evaluated and is planned
to be available in the spring of 2008. The tool works with Siemens'
unique CTVision(TM) System, a SOMATOM(R) CT Sliding Gantry on rails
combined with an ARTISTE(TM) or ONCOR(TM) Linear Accelerator. DAO
enables users to make on-line plan corrections based on actual
pre-treatment CT scans taken in the treatment room, while the patient
is on the linear accelerator's treatment table.

Siemens is also working on the development of a highly-efficient
single arc radiation treatment called Cone Beam Therapy (CBT)(i). The
combination of CBT with DAO-based planning software will help improve
tumor control for many disease sites, while sparing as much healthy
tissue as possible.
