MANUAL

In order to establish and maintain consistent image quality, a regular
evaluation of the image quality is advised.

The Drystar 5500 contains an automatic QC procedure for general
radiography applications (refer to 

 on page

) 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 (refer to 

 on page

). In this chapter we will discuss how to control the

quality of general radiography applications.

Local Regulations may require other procedures.

The Drystar 5500 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 (Refer to the

) has

several additional fields where the QC data can be filled in. This image should

be filed as part of the QC procedure.
