CHICAGO -- November 26, 2012

At the 98^th Scientific Assembly and Annual Meeting of the Radiological
Society of North America (RSNA), November 25-30 in Chicago, Siemens Healthcare
(Booth #831, East Building/Lakeside Center at McCormick Place, Hall D) is
introducing the ACUSON Freestyle™ ultrasound system that features wireless
transducers, eliminating the impediment of cables in ultrasound imaging. To
enable this pioneering technology, the system brings to the market a large
number of innovations, including acoustics, system architecture, radio design,
miniaturization, and image processing. The ACUSON Freestyle system will expand
ultrasound’s use in interventional and therapeutic applications, where the
technology provides numerous workflow and image quality advantages. The
development of wireless ultrasound is in line with the objectives of the
Healthcare Sector’s global initiative Agenda 2013 – specifically in the areas
of innovation and accessibility.

Transducer cables have always been a cumbersome necessity in ultrasound
imaging. Not only are they an impediment to fast and ergonomic examination
procedures, but they also present an infection control risk in sterile
interventional settings, even when they are covered in sterile sheaths.
“Siemens Healthcare is the first company to introduce an ultrasound system
that enables physicians to work with cable-free transducers,” says Jeffrey
Bundy, CEO of the Siemens Healthcare Ultrasound business unit. “The ACUSON
Freestyle system facilitates the use of advanced ultrasound technology into
clinical fields requiring a sterile environment, such as interventional
radiology, anesthesiology, critical care, cath lab, or emergency care.”
Wireless transducers can also expand ultrasound into new and emerging
applications such as administering nerve blocks, enhancing vascular access,
and improving target localization through ultrasound guidance during
therapeutic interventions and biopsies.

For image acquisition and processing, the ACUSON Freestyle system employs
advanced synthetic aperture imaging technology, an integration of proprietary
hardware and software that was specifically developed for the wireless signal
transmission of full-resolution digital image data at very high data rates.
Focusing on each pixel in the image, this method produces excellent image
quality throughout the field of view. This design reduces the transducer’s
power requirements, increasing battery life. Wireless real-time ultrasound
data transmission is further enabled through the proprietary development of a
novel ultra-wideband radio technology, which, operating at a high frequency of
7.8 Gigahertz, is not susceptible to interference with other electronic

Three wireless transducers are available for the ACUSON Freestyle system,
covering a range of general imaging, vascular, and high-frequency applications
such as musculoskeletal and nerve imaging. The user can operate the
transducers up to three meters away from the system, which includes an
ergonomic interface that enables remote control of scanning parameters from
within the sterile field. The ACUSON Freestyle system has a 38-centimeter,
high-resolution LED display. The system console can be mounted easily on a
lightweight cart and also operates on battery power.

The products mentioned here are not commercially available in all countries.
Due to regulatory reasons the future availability in any country cannot be
guaranteed. Further details are available from the local Siemens

Launched by Siemens Healthcare Sector in November 2011, Agenda 2013 is
atwo-year global initiative to further strengthenthe Healthcare Sector's
innovative power and competitiveness.Specific measures will be implemented in
four fields of action:Innovation, Competitiveness, Regional Footprint, and
People Development.

The Siemens Healthcare Sector is one of the world's largest suppliers to the
healthcare industry and a trendsetter in medical imaging, laboratory
diagnostics, medical information technology and hearing aids. Siemens offers
its customers products and solutions for the entire range of patient care from
a single source – from prevention and early detection to diagnosis, and on to
treatment and aftercare. By optimizing clinical workflows for the most common
diseases, Siemens also makes healthcare faster, better and more
cost-effective. Siemens Healthcare employs some 51,000 employees worldwide and
operates around the world. In fiscal year 2012 (to September 30), the Sector
posted revenue of 13.6 billion euros and profit of 1.8 billion euros. For
