The present protocol provides three approaches for dose assessment in mammography:
measurements on patients (chapter 1, appendix 1). This covers determination of entrance surface air kerma (ESAK) for patients employing either thermoluminescent dosemeters (TLDs), issued and read out by a central laboratory, or calibration of tube output;
measurements with a standard phantom (chapter 2, appendix 2). ESAK is determined for the standard phantom using TLDs from a central laboratory or calibration of tube output with an appropriate dosemeter;
determination of mean glandular dose (chapter 3, appendix 3). Average glandular dose (AGD) is calculated from ESAK using adequate conversion factors as a function of measured half-value layer (HLV). This can be determined either for the standard phantom or for a representative selection of patients. Chapters 1, 2 and 3 on the three approaches of dose assessment should be readable for doctors, radiologists, radiographers and screening managers. The corresponding appendices are intended to provide additional information on the dosimetric approaches. Appendix 4 provides a summary of dosimetric methods recommended in national protocols and tables to convert results according to national protocols into values according to the European protocol. Appendices 5 and 6 are mainly intended for those interested in additional scientific information.
