When the technologist adjusts the control panel to increase the kVp by a certain percentage and reduces the mAs to half, this represents application of the:
15% rule
Reproducibility Law
Reciprocity Law
Inverse Square Law
15% rule
Rationale: kVp and density are directly related; they are not directly proportional. If it is desired to double the density and mAs cannot be adjusted, kVp can be increased by 15%.
