Proposal for internal quality control protocol in term of tests frequency and image parameters:
A quality control (QC) protocol had been defined and used at the European Georges Pompidou Hospital (Paris,
France) from February until June 2016.
Parameters indicated in grey are declined from the EUREF protocol.
The reproducibility was tracked over the time from the first projection image in DBT.
All the others parameters were extracted from the reconstructed DBT images.
