Selenia Dimensions mammography system

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 3D Mammography technology. With the introduction of Selenia Dimensions, we launched the first commercially available system that delivers on the extraordinary promise of 3D mammography.

Over half of the U.S. News and World Report top 20 cancer hospitals offer Hologic 3D Mammography. 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 3D Mammography: Changing the paradigm in breast cancer screening

Hologic has always been at the forefront of breast cancer screening, so it's not surprising that we were the first to offer true 3D mammography. The revolutionary Selenia Dimensions system, which promises to set the new standard in mammography screening, offers:

  • Exceptionally sharp images.
  • Groundbreaking breast 3D mammography technology.
  • Seamless transition between imaging modes.
  • Advanced user tools to simplify operation.
  • Ergonomic design for patient comfort and ease of operation.

In addition, the Selenia Dimensions system provides these diagnostic advantages:

  • Earlier detection of breast cancers.1
  • Clearer lesion images.2
  • Reduction in the number of unnecessary biopsies, minimizing patient anxiety and unnecessary costs.1

Faster and lower dose 3D exams are now possible with the C-View software option.

Hologic has advanced mammography even further, giving radiologists the ability to reconstruct 2D images from Hologic 3D Mammography data without the need for 2D exposures. Images generated from C-View software can be used in place of traditional 2D images as part of the 3D breast exam. The 2D images and 3D slices are reviewed together to make a clinical decision or diagnosis. C-View software makes lower dose Hologic 3D Mammography exams possible — and the combined 3D and C-View exam offers superior clinical performance compared with 2D alone.3


Selenia Dimensions offers multiple workstations to meet your unique needs, incorporating the latest technologies to simplify workflow and facilitate high patient throughput. Each workstation offers:

  • A flexible platform that allows you to start with both 2D digital mammography and Hologic 3D Mammography for screening, diagnostic and interventional procedures, or with a 2D digital mammography-only system to which you can add Hologic 3D Mammography imaging with a simple software upgrade.*
  • User-friendly controls featuring intuitive icons and function screens.
  • Optimized system design for Hologic 3D Mammography imaging with proven results:

o    Rapid scans that take less than 4 seconds.

o    15-degree scan, providing high in-plane resolution.

o    Acquisition of 15 projection images (1 image/degree of arc) and filtered-back reconstruction, enabling rapid reconstruction of high quality images.

Not all mammography systems are the same. The combination of Selenia Dimensions lower dose 3D mammography and C-View software is clinically proven to be more accurate than 2D alone for all breast types. C-View software produces 2D images from Hologic 3D Mammography slices without 2D exposures.

Benefits include:

  • Rapid combined 2D/3D scans that take less than 4 seconds.
  • Less time under compression to improve patient comfort, while lowering the risk of motion.
  • Clinically superior exams with virtually the same radiation dose compared to standard 2D imaging.3

 The award-winning design of the Selenia Dimensions system with Acquisition Workstation (AWS) 8000 package offers:

  • Premium workstation with advanced ergonomics and workflow enhancements.
  • Biometric login, enabling the operator to begin an exam with pre-configured workflow preferences in place.
  • Ergonomically designed exposure switches on either side of acquisition system, with light pressure of the hand activating exposure, eliminating repetitive motion discomfort.


 The Selenia Dimensions system with Acquisition Workstation (AWS) 5000 package offers:

  • Ergonomic, motorized height adjustment.
  • Choice of paddles, accessories and license options.

The Selenia Dimensions Avia package offers:

  • Excellent 2D images on a cost-effective platform.
  • High-volume mammography screening or add-on options for diagnostic and interventional Hologic 3D Mammography* procedures.

*Additional purchase applies.


Streamlining workflow, the Selenia Dimensions system performs the imaging of tomorrow, today. All configurations offer the following features.

High-resolution display:

  • Images that can be instantly viewed on a 3MP DICOM-calibrated display, providing exceptionally fine detail.
  • Allows prior breast imaging studies to be recalled, making it possible to view new and prior images side-by-side.

Optimized face shield:

  • Retractable to help when positioning patients.
  • Stationary during 3D imaging, allowing patients to be positioned as they are for 2D imaging.

FAST Paddle system

  • Conforms to natural contours of the breast, providing greater comfort to the patient and more even compression across the entire breast.
  • All paddles used for 2D and 3D imaging.

Streamlined tube head:

  • Streamlined tube head and SID of 70 cm, making positioning easier and providing more space for interventional procedures.

Multiple procedure modes:

  • 2D only.
  • 2D + 3D.*
  • C-View 2D + 3D.
  • 3D only (for diagnostic use).*

Each system is capable of interventional procedures using the Affirm breast biopsy guidance system (link to Affirm system product page). This system offers both stereotactic and 3D biopsy procedure options.*
