Mammography

Programmers model normality to find pathologyThe development of algorithms that define disease is an established route in computer-aided detection. Some might argue it is the only route. But not Image Metrics. In sharp contrast to

GE Medical Systems is producing a mobile version of its Senographe 2000D digital mammography system. The mobile configuration includes the full-field digital system, an acquisition workstation for image review, and a patient changing area. The University

Five-year deal calls for technology sharingThe deal is done. Hologic and Siemens have finalized their partnership in digital mammography, cementing mutual sourcing agreements for components of a full-field digital system that were

The FDA issued Hologic an approvable letter in mid-July for its Lorad Selenia digital mammography system. The full-field product is based on an amorphous selenium detector plate developed by Direct Radiography, which Hologic purchased three years ago.

FOV and instant imaging minimize errorsMammography depends as much on operator skill as technology. Poor positioning directly affects image quality, reducing the chance for breast cancer detection and accurate staging. Certain

Detector for digital mammography delayedTrixell is ramping up production of its Pixium 4800, a dedicated digital detector for cardiac catheterization. Philips Medical Systems is already building the detector into its Integris

Full-field digital mammography (FFDM) has a slight edge over conventional screen-film systems when characterizing microcalcifications, according to German researchers. FFDM came out on top when compared to screen-film mammograms of patients with

Computer-aided detection software developed by R2 Technology can now be marketed as an integral part of the GE Senographe 2000D full-field digital mammography system, following FDA approval. This is the latest step in R2's pioneering efforts to make CAD

Hologic hopes to enter a strategic alliance with Agfa to help develop its amorphous selenium digital mammography system. The collaboration, which could be finalized in the next several months, would leverage Agfa's strength in image processing

Hologic exec declares new product DOAJust as one arm of Hologic prepares to begin marketing the company's finally approved full-field digital mammography system, another is preparing to make the product obsolete. Hologic announced

Customers shopping for full-field digital mammography systems have another product to consider. The FDA has cleared Fischer Imaging’s SenoScan for sale in the U.S. In making the announcement Sept. 25, Fischer executives predicted that a large

For years, proponents of digital mammography have focused on the inherent cost-effectiveness of digital mammography. But that may not be its best selling point. Increased efficiency and its effect on patient throughput could be the keys that open the

Business is booming for the maker of specialty digital mammography and x-ray imaging systems. In its second quarter, end July 1, the company reported revenue up $900,000 to $12.8 million compared with $11.9 million for the same quarter last year. Net

Full-field digital mammography is receiving a full-court press by imaging vendors, several of which are in various stages of device testing or FDA review. But regulatory approval is only the first hurdle. More serious is the challenge to show a clearcut

Just four months after filing a premarket approval application with the FDA, Fischer Imaging has received an approvable letter for its SenoScan full-field digital mammography system.Once final approval is received—Fischer executives hope as early

Specificity has long been the weak spot of computer-aided detection. Pattern-matching algorithms have traditionally marked everything suspicious, leading radiologists to complain that CAD systems did little more than redirect them to do a second read.CAD

The FDA has warned GE Medical Systems that certain procedures surrounding the manufacture, packaging, and shipping of GE’s digital mammography system are not adequate. The allegations, made in an April 10 warning letter, followed a routine
