Selenia® Dimensions® system’s 3D MAMMOGRAPHY™ exam: Simply a better mammogram.

What if we could find breast cancers earlier? See lesions more clearly? Reduce the number of unnecessary biopsies?

Questions like these inspired Hologic researchers and scientists to develop Hologic's 3D MAMMOGRAPHY™ technology. With the introduction of Selenia Dimensions, we launched the first commercially available system that delivers on the extraordinary promise of breast tomosynthesis.

Over half of the U.S. News and World Report top 20 cancer hospitals offer Hologic's 3D MAMMOGRAPHY™ technology. More than five million women to date in the United States have already been screened with this life-changing technology, which is now available in 50 states and in over 50 countries.

Hologic has always been at the forefront of breast cancer screening and offers the first and only breast tomosynthesis technology with proven superior clinical performance to 2D mammography. The revolutionary Selenia Dimensions system, which has set the new standard in mammography screening, provides:

  • Exceptionally sharp images

  • Seamless transition between imaging modes

  • Sophisticated user tools that simplify operation

  • Advanced clinical applications

  • The world’s first and only tomosynthesis-guided biopsy

  • Ergonomic design for patient comfort and ease of operation


In addition, the Selenia Dimensions system’s Genius 3D MAMMOGRAPHY™ exam is the only breast tomosynthesis that offers the following advantages over 2D mammography:

  • A 41% increase in invasive breast cancer detection

  • Up to 40% reduction in false positive recalls, minimizing patient anxiety and unnecessary costs


Fast, low-dose and clinically superior 3D MAMMOGRAPHY™ exams: Powered by C-View™ software.

Hologic has progressed breast cancer screening even further by producing 2D images from breast tomosynthesis data using C-View software, resulting in a Low Dose Genius 3D MAMMOGRAPHY™ exam with superior clinical performance compared with 2D alone. 


This Low Dose Genius 3D MAMMOGRAPHY™ exam is performed in a rapid <4 second scan time for greater patient comfort; and, low patient dose due to the elimination of 2D X-ray exposures. The generated 2D images and 3D™ slices are reviewed together to make a clinical decision or diagnosis as part of the Genius 3D MAMMOGRAPHY™ screening exam.
