The Fight Against Breast Cancer
Has A New Weapon
Digital Mammography
Over the past decade, there has been
tremendous progress in the science of mammography. New x-ray tubes,
filters, films, and computerized tools, along with improved
positioning and processing techniques, have significantly improved
the detection of clinically occult breast tumors.
Although mammography is currently
considered to be the best tool for early detection of breast cancer,
conventional film/screen imaging is still far from perfect; it
misses approximately 15% of lesions. This is particularly a problem
for women with radiographically dense breasts - between 15% and 50%
of all women, depending on the definition of density used. In such
cases, a false negative can result when the cancer is obscured by
overlying and surrounding fibroglandular tissue, or other
radiological information.
At the heart of this problem is a
fundamental limitation of film/screen mammography:
The fact that the detection, display
and storage devices are one and the same, making it impossible to
separately optimize each device. A long-awaited breakthrough in
mammography has arrived. GE Senographe 2000D Full Field Digital
Mammography System - a solution
that opens a window of tremendous opportunity for healthcare
facilities around the globe.
The result of tightly integrating
proven Senographe features with the World’s only Digital Flat
Panel Detector RevolutionTM, the Senographe 2000D has
been designed from the start for optimized breast imaging. Among its
most important qualities are :
• A single-piece flat-panel
digital detector to preserve image quality and reliability.
• A Rhodium anode and filter, for
improved penetration of dense breasts at low dose.
• Automatic Optimization of
Parameters, to take the guesswork out of parameter selection.
• A compact, bucky-sized
configuration to permit continued application of universally
accepted positioning techniques and imaging of important underarm
tissue.
• High speed and low dose to
accommodate the fast, multiple exposures required for future
advanced applications, such as 3D imaging, digital subtraction
angiography and tomosynthesis.
• A clear migration path to
Computer Aided Detection, with exclusive access to diagnostic
soft-copy ImageCheckertm CAD software.
• Customisable workstation for a
host of functional advantages - ability to manipulate image data
to facilitate the detection and characterization of obscure
radiological findings. Thanks to its digital nature, information
acquired can be processed by a variety of tools to improve its
analysis and communication.
