Affirm Prone Biopsy System

Affirm Prone Biopsy System

The first and only dedicated prone stereotactic biopsy system with 2D/3D™ imaging.

What are you looking for in a prone breast biopsy solution? The power to conduct both 2D and 3D™ Breast Biopsies with a single system? Superior imaging equal to today’s most advanced mammography systems? A faster, easier way to workFull 360˚ access to the breast? The power to improve your patients’ biopsy experience?

The Affirm prone breast biopsy system delivers it all.

The Affirm prone biopsy system expands Hologic's breast biopsy portfolio to include a dedicated prone biopsy system, complementing Hologic’s 3D MAMMOGRAPHY™ technology and Affirm upright biopsy accessory for the Selenia® Dimensions® mammography system. This portfolio equips hospitals and imaging centers with the options necessary to provide minimally invasive breast biopsies for a wide spectrum of patients. 


In breast biopsy, superior image quality and superior access are paramount to making it fast and easy to identify and confidently target lesions. We understand that the prone biopsy systems of the past can’t keep up with today’s state-of-the-art mammography systems.

That’s why the scientists at Hologic created the world’s first dedicated prone stereotactic biopsy system capable of both 2D and tomosynthesis-guided procedures. This new-generation solution elevates prone biopsy performance to a level never before possible.

The Affirm prone biopsy system delivers:

  • Stereotactic biopsy with Superior1 2D or 3D™ imaging using the same proven detector technology found in our Selenia Dimensions mammography system
  • A streamlined workflow designed to deliver faster procedures1
  • Easy, total access to the breast with full 360-degree access and an exclusive fully integrated lateral needle approach to facilitate reaching challenging lesions
  • Enhanced patient comfort through ergonomic design and an array of patient positioning aids

Hologic’s 3D™ Breast Biopsy option helps visualize lesions that are only seen under tomosynthesis while also reducing the number of steps needed for a procedure and lowering the radiation dose compared to a traditional 2D biopsy.


The Affirm Biopsy System is available in two configurations to meet your facility’s needs.

  • The 2D biopsy configuration provides traditional 2D stereotactic biopsy capabilities while also providing superior imaging1, a faster1 easier workflow, and improved1 access to the breast.
  • The 3D™ biopsy configuration provides all of the capabilities of the 2D configuration but also adds tomosynthesis guided biopsy.

Both Systems Include:

  • Bi-directional elevating patient support platform
  • Fully integrated and independently rotating tube-arm, biopsy arm, detector mechanism
  • Exclusive, Fully integrated lateral needle approach
  • 180° continuous C-arm rotation
  • Under table and Biopsy field work lights (LED, dimmable)
  • High resolution color touch screen Biopsy Control Module
  • DICOM: Worklist, Query/Retrieve, Storage, Storage Commitment, Print
  • 1 set of Paddles: 5 cm x 5 cm (biopsy window) standard, 6 cm x 7 cm Standard, 5cm x 5 cm axillary, 15 cm (total width) Lateral
  • Fine needle guide accessory
  • 1 stool with backrest

Adjustable Height Workstation:

  • Electronic lift mechanism (40.7 cm vertical travel)
  • Workflow Display monitor: 17” 1280 x 1024 resolution
  • 2 MP or 3 MP DICOM image display monitors 
  • Identify challenging lesions with a direct-conversion selenium detector and a 14.3 cm x 11.7 cm field of view that is more than 6.5 times larger than existing dedicated prone biopsy systems2 Broaden your view of targeted tissue with X-ray translucent paddles.
  • Streamlined user experience based on the software found in our Selenia® Dimensions® system.
  • Speed up procedures with an automated tube head that sweeps over the breast to acquire all necessary images with a single press of a button.
  • One-click-targeting when using Hologic 3D™ Breast Biopsy.
  • Get 360° total access to the breast to accommodate most lesion locations – with bidirectional patient positioning and 180° C-arm rotation.
  • Intuitive touchscreen Biopsy Control Module with 3-dimensional navigation aids that clearly displays the position of the biopsy device to guide the way during procedures.
  • Automate calculations – biopsy needle parameters are programmed into the system to display safety margins and relevant distance in real-time.
  • Exclusive fully integrated lateral needle approach. Go from standard to lateral needle approach in seconds even without releasing the patient from compression to save time and gain easy access to challenging lesions. No additional attachments required.
  • Arm-through procedure accessories including arm-rest and large 11 x 10.5 in table aperture make it fast and easy to comfortably position a patient and access challenging axillary lesions.
  • Maximum comfort package. Our ergonomically engineered cushions provide custom, targeted pressure-point support for most body types to improve the patient experience.
  • Advanced biopsy Acquisition Workstation with electronic height adjustment to help improve system ergonomics.
