New technology applies iterative and machine learning algorithms to provide a clearer, more concise three-dimensional (3D) breast reconstruction during digital breast tomosynthesis (DBT).
Siemens Healthineers High Definition (HD) DBT technology incorporates enhanced multiple parameter iterative reconstruction (EMPIRE) software, which builds on the company’s established DBT platform, offering a wide sweep of 50 degrees and a total of 25 projections. The wide range provides a perspective required for optimal depth resolution, which cannot be achieved with smaller angles. The state-of-the-art panel detector also offers readout at full resolution without the need for pixel binning.
EMPIRE technology also upgrades image quality by reduction of noise and artifacts, enhanced detection and display of micro-calcification morphologies, and improvements in subcutaneous tissue and skin line visualization. EMPIRE also includes Insight synthetic software, which visualizes tomosynthesis volumes in 2D and 3D as obtained from the EMPIRE 3D image set, providing surgeons with a functional navigational support tool that does not subject the patients to an additional radiation dose.
“The 50 degree angle and 25 projections provide better image quality,” said Ana Maria Rocha Garcia, MD, of Povisa (Spain). “3D imaging gives you more information and a wider angle reduces the effect of overlapping tissue, which is the main problem of 2D mammography. This allows for a better diagnosis.”
EMPIRE is available with the Mammomat Inspiration mammography system, a highly flexible platform that offers a tailored tomosynthesis solution that optimizes clinical outcomes by supporting screening, diagnostics, stereotactic biopsy, and DBT.
