Variable kVp charts use an optimum mAs value for each projection while fixed kVp charts use a specific kVp value for each projection

Variable kVp charts use an optimum kVp value for each projection while fixed kVp charts use a specific mAs value for each projection (correct)

Variable kVp charts use a specific kVp value for each projection while fixed kVp charts use an optimum mAs value for each projection

Variable kVp charts use a specific mAs value for each projection while fixed kVp charts use an optimum kVp value for each projection

More latitude for exposure error (correct)

Greater visibility of the spatial resolution

Higher overall image contrast

Small incremental changes in exposure techniques

A chart that uses a specific kVp value for each projection and varies the mAs according to the patient/part thickness

A chart in which mAs is the primary variable but kVp fluctuates within a range of ±4 kVp from the optimum level (correct)

A chart that uses a specific mAs value for each projection and varies the kVp by 2 to 3 kVp/cm for changes in patient/part size

A chart in which kVp is the primary variable but mAs fluctuates within a range of ±4 mAs from the optimum level
