The Mammography Quality Standards Act (MQSA) of 1992
requires that all mammography facilities in the United States
be accredited by an approved body. The American College
of Radiology is an MQSA approved accreditation body. To
receive MQSA accreditation, each facility must submit an image
of an ACR-approved phantom and, to maintain accreditation,
the phantom must be imaged weekly and records of
those images maintained. The ACR has approved the CIRS
Model 015 for use in the ACR Mammography Accreditation
Program.
The CIRS Model 015 Mammographic Accreditation Phantom
was designed to test the performance of a mammographic
system by a quantitative evaluation of the system’s ability
to image small structures similar to those found clinically.
Objects within the phantom simulate calcifications, fibrous
calcifications in ducts and tumor masses.

 

The phantom is designed to determine if your mammographic
system can detect small structures that are important in
the early detection of breast cancer. Test objects within the
phantom range in size from those that should be visible on
any system to objects that will be difficult to see even on the
best mammographic systems.
