Planar Systems and ATI Deliver State-of-the-Art Medical Imaging Solution; RoHS-Compliant Workstation FireGL(TM) Graphics Boards Advance Real-Time Medical Imaging.

BEAVERTON, Ore. -- Planar Systems, Inc. (NASDAQ:PLNR), a worldwide leader in flat-panel display systems, today announced it has selected ATI Technologies Inc. (TSX:ATY) (NASDAQ:ATYT) to provide advanced graphics processing technology for its medical imaging products. ATI is a global leader in the design and manufacturing of innovative 3D graphics, PC platform technologies and digital media silicon solutions. In an ongoing strategic effort for growth in digital imaging initiatives, Planar delivers the Dome AX4, built with the new ATI FireGL(TM) V3400, which is a commercially-available workstation graphics board created to dramatically accelerate the speed at which users can load, review, report and communicate patient cases with clinical colleagues.

With the integration of the ATI FireGL V3400, Planar's Dome EX series, designed for applications in radiology, cardiology, nuclear medicine (NM), positron emission tomography/computed tomography (PET/CT), magnetic resonance (MR), ultrasound (US), dermatology and the operating room (OR), allows users to experience enhanced visualization of various color modalities, 2D color imaging, image fusion and 3D imaging with faster delivery and image processing.

In addition, the introduction of the Dome AX4 is enabling the integration of 3D volumetric rendering and texturing, which require the use of Open GL or DirectX acceleration, into Picture Archiving and Communications Systems (PACS). This allows healthcare professionals to rapidly load and view multiple grayscale and color images in a variety of formats in real time.

"Planar continues to provide customers with multiple options integrating the latest in graphics processing technology," said Patrick Herguth, vice president and general manager of the medical business unit for Planar. "ATI's premier stature in the graphics controller market coincides with Planar's stature in diagnostic imaging displays. This collaboration provides the customer with a best-in-class product offering while complying with RoHS standards."

In July of this year, RoHS-compliancy standards will be enforced in Europe, with the U.S. to follow in 2007. Planar and ATI are committed to developing and providing products for the medical imaging market that comply with this new regulation, like the Dome AX4, ATI FireGL V3400.

"ATI is dedicated to the creation of innovative display technology for cutting-edge solutions and we're excited to be working with Planar, a leader in the PACS medical imaging market," said Joe Chien, general manager, Workstation Group ATI. "Powered by an advanced ATI FireGL Graphics Processor Unit, the FireGL V3400 enables Planar to provide its customers with unprecedented image fidelity, performance and flexibility."

ATI FireGL V3400 graphics controller boards will be offered with Planar's Dome series: E2, E2c, E3, E3c and E4c, as well as the P1 Bundle and P2 Bundle, providing the ultimate in 3D acceleration capability. This ATI next-generation card provides stability and quality to the Dome AX4 via extended driver and technical support and long-term manufacturability.

The Dome EX line will be showcased at the Society for Computer Applications in Radiology (SCAR) show April 27-30, 2006, in San Antonio, Texas, at Booth #109. Please visit the booth or contact Niccole Muraca at 781-464-2537 or [e-mail] if you are interested in speaking with a Planar representative at the show.
