The Drystar 5302 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. Local Regulations may require other procedures. The Drystar 5302 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. The results of these tests are recorded on Quality Control Charts. The QC image (Refer to ‘QC test image’ on page 52) has several additional fields where the QC data 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 75. 2831A EN 20041201 Advanced operation (key-operator mode) 47 DRYSTAR 5302 USER MANUAL Establishing the reference values and verifying image quality After installation of a new Drystar 5302 and before initial use you must establish Quality Control aim values. These values will be used as the base line for comparison when daily Quality Control is done. These values should be determined again after major service, repair or software update. The following Quality Control aim values must be determined: • The daily operating density levels. Refer to ‘Establishing the daily operating reference density levels’ on page 49. • Drystar 5302 image geometry. Refer to ‘Establishing the image geometry reference values’ on page 52. Once Quality Control aim values are established you must evaluate the Spatial Resolution, the Artifact Levels and the Low Contrast Visibility to determine if the image quality is acceptable. Refer to ‘Verifying Acceptable Spatial Resolution, Artifact Levels and Low Contrast Visibility’ on page 54. The Quality Control aim values, the Spatial Resolution and Artifact Levels and the Image Geometry values are all recorded on the Quality Control charts. Refer to ‘Quality Control Charts’ on page 75. On these charts, the following test conditions are also recorded: • The type and serial number of the Drystar 5302. • The type and emulsion number of the film used to determine the reference values. • The time (day, month, year) that the values were established. Before you can establish the daily operating levels, the Drystar 5302 must be switched on for at least 15 minutes and it must be calibrated as well. Refer to ‘Switching on the Drystar 5302’ on page 30 and ‘Performing the calibration procedures’ on page 97 of the Drystar 5302 Reference manual. 48 Advanced operation (key-operator mode) 2831A EN 20041201 DRYSTAR 5302 USER MANUAL Establishing the daily operating reference density levels This procedure enables you to establish the base line values for: • Low density • Mid density • High density The densitometer of the Drystar 5302 is calibrated at installation.

Make sure to measure distance A from the left edge of the left line to the right edge of the right line and distance B from the upper edge of the upper line to the lower edge of the lower line. We strongly recommend using a 30 cm (12-inch) machinist scale with 0.5 mm divisions (1/64 inch). 52 Advanced operation (key-operator mode) 2831A EN 20041201 DRYSTAR 5302 USER MANUAL Record these values as reference dimensions A ref and B ref on the Drystar 5302 Chart 4 (‘Drystar 5302 Geometric Consistency Control Chart’). Refer to ‘Quality Control Charts’ on page 75. These charts will be used for the annual quality test. For more information, refer to ‘Performing the Annual QC tests’ on page 58. Save this film for future reference. 2831A EN 20041201 Advanced operation (key-operator mode) 53 DRYSTAR 5302 USER MANUAL Verifying Acceptable Spatial Resolution, Artifact Levels and Low Contrast Visibility Good viewing conditions are important for the correct interpretation of both diagnostic and test images. Make sure that the lightbox intensity (luminance) is between 2000 and 4000 cd/m² (4500 and 6500 °K). Use a magnifying glass and use shutters to collimate. Make sure the ambient light is low. Print the QC Test image or use the previously printed QC Test image used to establish the daily operating density levels. Visually check the QC test image for artifacts: no significant disturbing artifacts should be visible. Check the spatial resolution in each of the three ovals. Within each oval there are three groups, each having five dots. All five dots of each group must be visible with a magnifying glass. The smallest cluster of 5 dots are only visible if the viewing conditions are good. Record these values at the top of the Drystar 5302 Chart 3 (Drystar 5302 Artifacts and Spatial Resolution Control Chart). Refer to ‘Quality Control Charts’ on page 75. Check the Low Contrast Visibility at both the high (100 / 95%) and low end (0 / 5%) of the density scale. You should be able to see the circle in the square (refer to item 1 on the ‘QC test image’ on page 52) and the upper circle (refer to item 2 on the ‘QC test image’ on page 52). These charts will be used for the weekly quality test. For more information, refer to ‘Performing the Weekly QC tests’ on page 57. In case of significant artifacts or insufficient spatial resolution, the reason must be found and the problem solved before any further clinical films can be printed. Refer to ‘Preventive maintenance schedule’ on page 59 and ‘Maintaining image quality and resolving image quality problems’ on page 173 of the Drystar 5302 Reference manual, or call your local Agfa service organization. 54 Advanced operation (key-operator mode) 2831A EN 20041201 DRYSTAR 5302 USER MANUAL Performing quality control (QC) tests The following procedures must be performed daily, weekly or annually as indicated. The reason for performing quality control tests is to determine if any significant image quality variation or deterioration has occurred which may require corrective action. Comparing the results of the tests with the reference values previously established does this. This procedure allows the operator to take the necessary preventive actions before any image quality loss can take place. Performing the daily QC test This test must be performed every day before any clinical film can be processed. Turn on the Drystar 5302 and wait at least for 15 minutes.

In case the measure results are not within the aim values, the reason for the unacceptable density variations must be identified and resolved before any further clinical films can be processed. This may include repeating the film calibration procedure. For possible causes of non-compliance and the respective actions, refer to ‘Preventive maintenance schedule’ on page 59 and ‘Maintaining image quality and resolving image quality problems’ on page 173 of the Drystar 5302 Reference manual. 56 Advanced operation (key-operator mode) 2831A EN 20041201 DRYSTAR 5302 USER MANUAL Performing the Weekly QC tests Spatial Resolution, Artifact Test and Low Contrast Visibility To identify artifacts and verify spatial resolution you must perform the following test weekly or as needed for troubleshooting image quality problems. Good viewing conditions are important for the correct interpretation of both diagnostic and test images. Make sure that the lightbox intensity (luminance) is between 2000 and 4000 cd/m² (4500 and 6500 °K). Use a magnifying glass and use shutters to collimate. Make sure the ambient light is low. Check the QC test image visually for artifacts: no significant disturbing artifacts should be visible. Check the spatial resolution. The test film also shows three squares which each contains an oval. These 3 ovals contain 3 groups, each having 5 dots. All five dots of each group must be visible with a magnifying glass. The smallest cluster of 5 dots are only visible if the viewing conditions are good. Check the Low Contrast Visibility at both the high (100 / 95%) and low end (0 / 5%) of the density scale. You should be able to see the circle in the square (refer to item 1 on the ‘QC test image’ on page 52) and the upper circle (refer to item 2 on the ‘QC test image’ on page 52). Record these values on the Drystar 5302 Chart 3 (Drystar 5302 Artifacts and Spatial Resolution Control Chart). In case of significant artifacts, insufficient spatial resolution or failure of any other recommended QC tests, the cause of the problem must be identified, and corrective action must be taken before the Drystar 5302 can be used for any further clinical imaging. Refer to‘Preventive maintenance schedule’ on page 59 and ‘Maintaining image quality and resolving image quality problems’ on page 173 of the Drystar 5302 Reference manual, or call your local Agfa service organization for assistance. 2831A EN 20041201 Advanced operation (key-operator mode) 57 DRYSTAR 5302 USER MANUAL Performing the Annual QC tests Geometric Consistency Test To be able to notice fluctuations in image size and aspect ratio, you must perform this procedure once a year. First, perform the daily test. Use the QC test image of the weekly test and measure the dimensions A and B of the geometric square. Refer to ‘Establishing the image geometry reference values’ on page 52. Make sure to measure distance A from the left edge of the left line to the right edge of the right line and distance B from the upper edge of the upper line to the lower edge of the lower line. We strongly recommend using a 30 cm (12-inch) machinist scale with 0.5 mm divisions (1/64 inch). Record these values as measured dimensions A and B on Chart 4 (‘Drystar 5302 Geometric Consistency Control Chart’). Compare the measured A and B dimensions with the reference dimension values, A ref and B ref on the Drystar 5302 Chart 4 (‘Drystar 5302 Geometric Consistency Control Chart’). The differences between measured dimensions of A and B and the reference values A ref and B ref should be less than or equal to 1.0%. Check for image distortion. Calculate the aspect ratio by dividing A by B. The result must be 1 +/- 0.01 If the image size or distortion values are outside of limits, contact Agfa service to resolve the problem. 58 Advanced operation (key-operator mode) 2831A EN 20041201 DRYSTAR 5302 USER MANUAL Preventive maintenance schedule The Drystar 5302 is designed for trouble-free service.
