Quality control for general radiography applications
In order to establish and maintain consistent image quality, a regular
evaluation of the image quality is advised.
The printer contains an automatic QC procedure for general radiography
applications and has been designed to comply with the grayscale reproduction
constancy test, according to the international standard IEC 1223-2-4. If the
option for the mammography application is activated, another QC procedure
is available for the mammography application. This QC procedure has been
designed to comply with the Mammography Quality Standards Act (MQSA) of
the FDA. In this chapter we will discuss how to control the quality of general
radiography applications.
Local Regulations may require other procedures.
The printer Hard Copy quality control procedures consist of two main steps:
• Before initial use, establishing a number of reference values that will be
used for further follow-up and verifying initial image quality.
• After establishing these values, performing regular daily, weekly and
annual quality tests.
The results of these tests are recorded on Quality Control Charts.
The QC image has several additional fields where the QC data can be filled in.
This image should be filed as part of the QC procedure.
