R2 introduces smarter CAD algorithm and workflow for mammography
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
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.”
