Product Review

The stage was set for “Medicine’s Digital Transformation,” with thousands of visitors and exhibitors coalescing at the 88th Scientific Assembly and Annual Meeting of the Radiological Society of North America (RSNA of Oak Brook, Ill.), Dec. 1-5, 2002, in Chicago’s sprawling McCormick Place. The show — and its theme — recognized the role digital technology is playing in radiology’s expanding influence in healthcare.

Hologic Inc.’s (Bedford, Mass.) Lorad Selenia full-field digital mammography system made its RSNA debut fresh off its October 2002 premarket approval (PMA) supplement from the FDA. Selenia uses Hologic’s DirectRay amorphous-selenium, direct-to-digital image receptor to generate digital mammographic images that can be used for screening and diagnosis of breast cancer. Hologic’s DirectRay division (Newark, Del.) produces the patented digital image receptor.

The company also plans to tap into the existing upgrade marketplace, which includes more than 3,000 installed Lorad M-IV screen-film mammography systems that can be converted to direct-to-digital capability in the field.

Canon Medical Systems (Irvine, Calif.) debuted several new products at the show.

Designed for all general radiography applications, the Canon CXDI-40G Digital Radiography System can be installed in a table or used with an upright or universal stand. The system combines the Canon amorphous silicon flat panel sensor with a 17-by-17-inch image area with smaller and lighter housing. This allows a wider range of applications and more possibilities for retrofitting with older systems.
