Mammo 156D Stereo Phantom

Maintain system quality and compliance.

  • Comprehensive stereotactic biopsy system accreditation
  • Comply with MQSA (FDA), ACR1 requirements
  • Manufactured only by Gammex

Like the Mammo 156 Phantom, the Mammo 156D Stereo Phantom is ACR-accredited, and backed by Gammex’s thirty-plus years of servicing the mammography QA industry.

The phantom supports monitoring of mammography systems used for biopsy and localization, and simulates radiographic characteristics of compressed breast tissue.

Evaluate Image Quality
Mammo 156D Stereo Phantom, by design, contains test objects that are both visible on any system and difficult to see on the best stereotactic mammography systems.


Strengthen your mammography QA program, help improve patient outcomes, and comply with MQSA and ACR guidelines.
