Mammo 156 Stereo Phantom

Maintain system quality and compliance.

  • Use for comprehensive patient evaluation, including stereotactic biopsy
  • Comply with MQSA (FDA), ACR, EUREF, IAEA and ACPSEM guidelines

Like the Mammo 156 Phantom, the Mammo 156 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 156 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.

The Mammo 156 Stereo Phantom for Accreditation
  • Provides quick detection of objects from 0.20 to 1.00 mm
  • Designed to hang on the biopsy system detector during rotation

Remain Compliant
The Mammo 156 Stereo Phantom mimics breast tissue. Imbedded objects mimic breast diseases, micro-calcifications, fibrous structures and tumor masses.
