7. RADIOGRAPHER’S QUALITY CONTROL TESTSThe tests provided here form a QC programme for the radiographer and in most cases offer a replacement fortests that are in the manufacturer’s programme. It is not necessary to perform both sets of tests. This programmedoes not include maintenance or calibration procedures. Maintenance and calibration activities should be performedby the appropriate individual according to the manufacturer’s instructions.A brief description of the methodology to be undertaken when performing the radiographer’s QC tests isprovided in this section (Table 4). The tests do not necessarily have to be performed in the order in which theyappear in this publication. The preferred order will depend on various factors relating to the mammography facilityas well as the preferences of the individual performing the testing, always keeping in mind that the results of onetest may affect the execution of others. Data collection sheets are found in Annex I and are available in electronicformat, along with other information relevant to testing of digital mammography, on the IAEA web site at:http://humanhealth.iaea.orgTABLE 4.
