Although late to relinquish its reliance on film, mammography is beginning to enjoy the fruits of digital technology. Mammography manufacturers are adding automated analytical tools to improve breast cancer detection and enhance workflow. They are also showing high-resolution multimodality workstations to allow side-by-side comparisons of breast images captured with ultrasound, MR, and CT as well as mammography. Visible on the horizon is volumetric breast tomosynthesis.
A leader in women's health, Fischer Imaging was a pioneer of digital technology in mammography. The company commercialized one of the first digital stereotactic biopsy systems and followed with the introduction in 2001 of its SenoScan TrueView digital scanning mammography system. Standard capabilities onboard the SenoScan include patented slot-scanning technology, which allows an industry best 25-micron native resolution and reduced x-ray dose, as well as curved breast support for patient comfort. Fischer has since added computer-aided detection capabilities and is developing a high-resolution flat-panel display for its digital mammography review workstation.
GE Medical Systems/Instrumentarium Imaging
At the first major radiology meeting since the Oct. 9 acquisition of Instrumentarium Imaging, GE Medical Systems showcased its expanded portfolio of mammography products, which comprises all commercially available mammography systems from the two companies. Included is stereotactic capability across all levels of Instrumentarium's film-based line.
With the idea of providing a suite of breast imaging products that extends beyond x-ray-based acquisition systems, Hologic has added capabilities in ultrasound and breast MR, while enhancing breast biopsy and CAD capabilities. At the RSNA meeting, the company unveiled the results of collaborative agreements with Aloka, R2 Technology, Confirma, and Suros, each of which were negotiated over the last six months. The highlight of the show was the breast tomosynthesis add-on for the Selenia full-field digital mammography system.
Siemens Medical Systems
The German multimodality company has targeted breast imaging innovations in x-ray mammography. At the RSNA meeting, the company displayed products introduced earlier in the year, as well as technologies still in the pipeline.
