Mammo 156 Phantom

The gold standard QA solution for breast health.

  • Required standard for image quality evaluation
  • Measure and monitor mammography systems’ signal to noise, resolution and image quality1
  • Simulate radiographic characteristics of 4.2 cm compressed breast tissue
  • Help improve patient outcomes


When the U.S. mandated mammography QA requirements via the the Mammography Quality Standards Act (MQSA), medical physicists, the ACR and the FDA worked with Gammex to design what is known today as the Mammo 156 Phantom.

The Mammo 156 phantom helped establish the mammography repeatability and reproducibility standard. With this resource, any technologist (radiographer) on any machine can provide the same image set to help detect breast cancer.


The phantom mimics breast tissue. It is a feedback mechanism that provides a framework for constant improvement in early detection and mortality reduction. Imbedded objects mimic breast diseases, micro calcifications, fibrous structures and tumor masses.

Evaluate Image Quality
The Mammo 156 Phantom must be imaged weekly to maintain accrediation.

The Mammo 156 Phantom for Accreditation

  • Quick detection of objects from 0.16 to 2.0 mm
  • 4 mm acrylic disc included to establish and monitor density differences
  • First MQSA-approved mammography phantom

Maintain Accreditation
Clinical and technical publications reference the Mammo 156 Phantom more than any other mammography phantom.
