Air Kerma and AEC Reproducibility Annual Quality Control Test

Policy Guidance Help System logo

Citation:

900.12(e)(5)(v): Breast entrance air kerma and AEC reproducibility. The coefficient of variation for both air kerma and mAs shall not exceed 0.05.

Questions:
  1. Must medical physicists test all AEC detectors for AEC reproducibility in mammography units with multiple AEC detectors in a single cassette holder (bucky)?
  2. Must medical physicists test AEC reproducibility in all clinically used AEC modes?
