Validity of the kVp(s) Used in Mammography Equipment Evaluation Testing

If the medical physicist survey report contains a mammography equipment evaluation for a new x-ray unit (i.e., the unit's first survey), be aware that, at the time of the mammography equipment evaluation, the physicist may not have known the exact kVp that the facility would be using for imaging the average breast. By the time of your inspection, the facility will probably have established this typical clinical value and it may differ from the value(s) the physicist used during the mammography equipment evaluation.

During the mammography equipment evaluation testing, if the physicist used a kVp that is different from what the facility is now using as the "average clinical kVp," the facility should not be cited for survey report inspection questions which ask "Done at the kVp normally used clinically?" as long as the kVp(s) that was tested is within the usual range of kVp's used for mammography of an average breast.
