    CHICAGO, Nov. 29 /PRNewswire/ -- R2 Technology, Inc., the recognized
 leader in computer-aided detection (CAD) technology for medical imaging, today
 announced the introduction of the ImageChecker(R) DMax CAD system, here at the
 90th Scientific Assembly and Annual Meeting of the Radiological Society of
 North America (RSNA), November 28-December 2.  Engineered to enhance workflow,
 the ImageChecker DMax system is powered by a new high volume, high performance
 laser scanner, developed collaboratively by R2 and Array Corporation USA, and
 offers twice the case throughput of other CAD systems while delivering
 superior image quality.
     R2 also announces an exclusive agreement with Array Corporation USA for
 this new laser film scanner, engineered specifically for the ImageChecker DMax
 system. Array was selected for this initiative "because of its long history
 and reputation for providing exceptional image quality and performance, and
 its ability to bring ImageChecker to the highest end of the technical
 spectrum, for customers demanding the most superior image quality possible,"
 stated William J. Mercer, president and CEO of R2 Technology. "The Array laser
 scanner provides the best penetration of high density film available,
 resulting in better images for CAD processing and review."
     Able to scan a mammography film every 30 seconds, the unique, ergonomic
 design of this mammography CAD processing system provides maximum efficiency
 and ease of use.  The ImageChecker DMax system has the smallest footprint R2
 has ever offered, providing high-density, high performance CAD.
     The ImageChecker DMax is built around Array's latest laser film digitizer,
 a 50-micron resolution, noise-reducing system capable of penetrating films up
 to density OD4.3. The superb performance of the film scanner is directly
 responsible for the superior quality of images archived by ImageChecker DMax's
 DigitalNow feature, which allows clinics to archive the digitized film images
 to PACS. Image quality is particularly important when the archived images are
 to be used later for comparison purposes on softcopy review workstations.
     "The ImageChecker DMax is named after the blackest part of a mammography
 film, that of the highest optical density, often referred to as Dmax," said
 Julian Marshall, principal engineer for R2 Technology. "Combined with the
 Array technology's superior penetration of high density film, the new high
 performance DMax system provides the best possible CAD images and is ideal for
 use by high volume mammography clinics that demand proven clinical value and
 maximum productivity."
     Computer-aided detection is used by increasing numbers of radiologists as
 "a second pair of eyes" when reading a mammogram. Clinical trials demonstrated
 that use of the ImageChecker system could result in earlier detection of up to
 23.4 percent of the cancers currently detected with screening mammography.
     The ImageChecker system from R2 Technology was the first CAD system
 approved by the FDA for use with mammography. Since 1998, R2 Technology has
 received 17 supplemental approvals for technological and clinical advances.
 To date, more than 1,500 ImageChecker CAD systems have been shipped worldwide
 and some eight million women have their mammograms interpreted annually with
 the aid of this leading CAD technology for the early detection of breast
     "We are pleased to partner with R2 Technology, each of us representing the
 high end of our core disciplines, to create the highest performing CAD system
 on the market," said Thomas J. Nardozzi, president of Array Corporation USA.
 "Powered by the new Array laser film scanner, the DMax produces superior
 quality images at twice the speed of other CAD systems. High quality scanners
 like Array's are critical for analog sites as well as centers that are
 transitioning to digital and need the ability to compare digitized priors side
 by side in a digital format."
     About Array Corporation USA
     Array Corporation USA provides technically superior solutions for
 capturing and communicating image data, and helps increases clinical
 productivity with digital scanning speed, performance and reliability. Using
 precise optics and a helium neon laser, Array scanning technology scans 14x17
 film at 2K resolution in seven seconds, almost four times faster than its
 nearest competitor. It provides a true optical density of up to 4.3 with an
 accuracy of .002, while the nearest digitizer can achieve only about 3.7 OD.
 With a variable sampling pitch that changes spot size from 50 microns to 500
 microns in one micron steps, the 2905 easily covers all possible uses for film
 digitization. Since its establishment in the U.S. in 1998, Array Corporation
 USA has cultivated a broad, nationwide network of validated vendors,
 authorized sales and service distributorships and direct end user clients. For
