Monochrome Monitors for Mammography
Foreword
Purpose of this Document
This document is for Monochrome Monitors for Mammography, diagnostic display
monitors to perform the Quality Control (QC) tests to meet the guidelines / regulations
of Mammography Quality Standards Act (MQSA) for the reading of the digital
mammographic images. This document describes the procedure for performing the
Quality Control (QC) tests for Monochrome Monitors for Mammography, diagnostic
display monitors based on the guidelines / regulations of Mammography Quality
Standards Act (MQSA).
Scope of this Manual
This document is referenced when conducting the Quality Control (QC) tests to
Monochrome Monitors for Mammography, diagnostic display monitors based on the
guidelines / regulations of Mammography Quality Standards Act (MQSA) for the reading
of the digital mammographic images through the full-eld digital mammography (FFDAM)
system.
Regulatory Considerations
For the facilities under the MQSA regulations, application of this manual is MANDATORY.
Failure to follow these quality assurance procedures can result in loss of MQSA
certication at facilities subject to the MQSA regulations. For the facilities under the
MQSA guidelines, application of this manual is RECOMMENDED. Otherwise, the
facilities may identify other ways of meeting MQSA requirements.

specied in the data form.
3. Adjust the room conguration if the current reading room conguration differs
from the one established as optimal in the data form. (For example, if desk lights
were specied to be turned off, turn them off, or, if curtains were specied to be
closed, close them.)
4. Complete the record of the check on the form 1 in this manual.
