R2 introduces smarter CAD algorithm and workflow for mammography products

10 June 2005

Sunnyvale, Calif. USA. R2 Technology, Inc., a leader in computer aided detection (CAD) technology for the earlier detection of breast cancer, has introduced its new Version 8.0 CAD algorithm, featured across R2’s ImageChecker Mammography product line.

V8.0 incorporates R2’s most intelligent CAD algorithm to date and numerous other product innovations. The V8.0 Gold Standard CAD algorithm, recently approved by the U.S. Food and Drug Administration (FDA), delivers significant improvements in detection performance versus prior releases.

“Version 8.0 continues our tradition of providing high-quality, innovative CAD solutions,” said John Pavlidis, R2 Technology’s president and chief executive officer. “With this release, we further address radiologists’ diverse and evolving clinical, workflow and technological needs.”

The ImageChecker V8.0 algorithm takes CAD to the next level, with far better Free-Response Receiver Operating Characteristics (FROC) performance. Data submitted to the FDA showed that R2’s new system provides a lower false marker rate at any given sensitivity. For instance, there are only 1.5 false marks per normal case at the 91 percent sensitivity level. "There has been a noticeable improvement in accuracy with fewer false positive markings per case," said Dr. Bruce F. Schroeder, Director of the Eastern Radiologists Breast Imaging Center in Greenville, NC. "Most screening cases are normal, so R2's lower false marker rate saves me time while its sensitivity has the potential to find even more breast cancers."

R2 also announced further V8.0 enhancements for improved workflow. For example, R2’s new EmphaSize CAD markers are designed to draw radiologists’ attention first to those mammographic features the algorithm deems to be the most indicative of malignancy. Other workflow enhancements include R2’s new “Greenlight” user interface, an easy-to-use touch-screen system that enables technologists to process films quickly and monitor film-scanning progress from a distance, without interrupting other work.

“R2’s ImageChecker Mammography CAD system gives radiologists additional confidence that they are detecting more potential cancers earlier,” said Mr. Pavlidis. “Version 8.0 is the most accurate, most intuitive and easiest to use R2 mammography CAD system ever.”
