Which of the following describes a variable kVp technique chart?
mAs is increased with each centimeter increase of the part
only kVp is increased while the mAs stays constant
kVp is increased a step and mAs is decreased a step
both mAs and kVp are increased with part thickness
only kVp is increased while the mAs stays constant
Rationale: Variable kVp technique charts use a constant mAs while the kVp is increased as part thickness increases. This chart is not often applied with consideration of increased scatter production with increased kVp values.
