Updated version of European breast tomosynthesis QC protocol (version 1.03)

Changes compared to version 1.01:

  • The dose reference values have been changed to limiting values.
  • The limiting dose value for 20 mm PMMA thickness has changed from 1.0 mGy to 1.2 mGy. This has been done because feedback was received and was noted that the value of 1.0 mGy was difficult to achieve with sufficient image quality for DBT systems.
  • Some text has been added regarding the mode in which mages have to be made in some methods of measurement.
