Tomosynthesis is a pseudo-3D breast imaging method, which hasn\u2019t\npreviously had national quality control guidelines despite its increasing usage.\n\nThe purpose of this thesis was to establish national quality control guidelines in tomosynthesis together with several hospitals, manufacturers and the Finnish Radiation and Nuclear Safety Authority. Based on the current international guidelines for tomosynthesis and national guidelines for 2D-mammography a selection of potential quality control tests were chosen, and their suitability was evaluated based on different criteria, such as the purpose and complexity of the test, and equipment and time required. Measurements were made to confirm these results, and the chosen tests were also executed on five different mammography systems. As a result, 12 quality control tests are recommended to be performed as a part of general quality control in mammography. The first draft of these guidelines can be found from attachment B.
