Quality Control for general radiography applications
In order to establish and maintain consistent image quality, a regular
evaluation of image quality is advised.
The printer contains an automatic QC feature that 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. In this chapter we will discuss how to control the
quality of general radiography applications.
Local Regulations may require other procedures.
The QC procedure consists 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.
Note
:
Repeat the two main steps of the Hard Copy quality
procedures for each input tray loaded with general radiography
films.
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.
