June 27, 2013 – A mammography
system designed to lower patient dose
by up to 30% without compromising image quality received 510(k) the Food and
Drug Administration (FDA) clearance.
Healthcare’s MAMMOMAT Inspiration Prime Edition is indicated for screening,
diagnostics, and biopsy. The system is engineered to lower dose by replacing
the standard scatter radiation grid with a new algorithm for progressive image
reconstruction. Capable of identifying scatter-causing structures and
calculating a corrected image, this new algorithm potentially enables complete
use of primary radiation so physicians can achieve high-quality images using
x-ray breast imaging, radiation passes through the examined breast to a
detector. Primary radiation supplies the information needed to provide the x-ray
image, while scattered radiation is absorbed by special grids positioned
between the breast and the detector. Unfortunately, since these scatter grids
also absorb a portion of the all-important primary radiation, physicians must
utilize a higher dose
to obtain images of desired quality. The ability to minimize patient dose
is important, as women are encouraged to undergo regular mammography screening.
new reconstruction algorithm for the MAMMOMAT Inspiration system – known as
Prime (Progressive Reconstruction, Intelligently Minimizing Exposure) – eliminates
the need for the scatter radiation grid of conventional mammography systems.
The Prime algorithm corrects the scattered radiation by identifying
scatter-causing structures and recalculating the image, leaving intact the
primary radiation upon which radiologists rely. For this reason, the design of
the MAMMOMAT Inspiration Prime Edition obviates the need for a grid, and lower
patient doses are sufficient to generate high-quality breast images. The
grid-free imaging technology of the MAMMOMAT Inspiration Prime Edition reduces
dose up to 30 percent compared to its predecessor model, depending on the
thickness of the patient’s breast tissue.
MAMMOMAT Inspiration Prime Edition is based on the modular MAMMOMAT Inspiration
platform has been used by hospitals and physicians offices since 2007.
