872852 A EN 20070205DRYSTAR AXYSQuality Control for general radiography applications (DT 2 B & DT 2 C)In order to establish and maintain consistent image quality, a regular evaluationof image quality is advised.The Drystar AXYS contains an automatic QC procedure for general radiographyapplications and has been designed to comply with the grayscale reproductionconstancy test, according to the international standard IEC 1223-2-4. If theoption for the mammography application is activated, another QC procedure isavailable for the mammography application (refer to “Quality control for mam-mography application (DT 2 Mammo) (optional)” on page 104. In this chapterwe will discuss how to control the quality of general radiography applications.Local Regulations may require other procedures.The Drystar AXYS Hard copy quality control procedure consists of two mainsteps:QBefore initial use, establishing a number of reference values that will be used for further follow-up and verifying initial image quality. Refer to “Establishing the reference values and verifying image quality for gen-eral radiography applications (DT 2 B and DT 2 C)” on page 88.QAfter establishing these values, performing regular daily, weekly and annual quality tests.Refer to “Quality Control for general radiography applications (DT 2 B &DT 2 C)” on page 87.The results of these tests are recorded on Quality Control Charts.The QC image (Refer to “QC test image for general radiography applications(DT 2 B and DT 2 C)” on page 90) has several additional fields where the QCdata can be filled in. This image should be filed as part of the QC procedure.For more information, please refer to “Quality Control Charts” on page 149.Note: Repeat the two main steps of the Hard Copy quality procedures for each input tray loaded with DT 2 B and/or DT 2 C films.
88 2852 A EN 20070205DRYSTAR AXYSEstablishing the reference values and verifying image quality for general radiography applications (DT 2 B and DT 2 C)After installation of a new Drystar AXYS and before initial use you must estab-lish Quality Control aim values. These values will be used as the base line forcomparison when daily Quality Control is done. These values should be deter-mined again after major service, repair or software update.The following Quality Control aim values must be determined:QThe daily operating density levels. Refer to “Establishing the daily operating ref-erence density levels for general radiography applications (DT 2 B and DT 2 C)” on page 91.QDrystar AXYS image geometry. Refer to “Establishing the image geometry refer-ence values for general radiography applications (DT 2 B and DT 2 C)” on page 95.Once Quality Control aim values are established you must evaluate the SpatialResolution, the Artifact Levels and the Low Contrast Visibility to determine ifthe image quality is acceptable. Refer to “Verifying Acceptable Spatial Resolu-tion, Artifact Levels and Low Contrast Visibility for general radiography applica-tions (DT 2 B and DT 2 C)” on page 96.The Quality Control aim values, the Spatial Resolution and Artifact Levels andthe Image Geometry values are all recorded on the Quality Control charts. Referto “Charts for general radiography QC” on page 150.
892852 A EN 20070205DRYSTAR AXYSOn these charts, the following test conditions are also recorded:QThe type and serial number of the Drystar AXYS.QThe type and emulsion number of the film used to determine the reference val-ues.QThe type of densitometer used.QThe time (day, month, year) that the values were established.WARNING: Before you can establish the daily operating levels, the Drystar AXYS must be switched on for at least 15 minutes and it must be calibrated as well.
