establishing a variable kVp scale. 1. produce initial phantom images-a phantom in a variable depth water bath simulates the various part thicknesses. 2. select optimal phantom image-do not vary kVp but instead, vary mAs-using a PEP (pt equivalent phantom) in order to eliminate the need for pt exposures.3. Extrapolate technique chart according to selected exposure system guidelines-steps should be formed in groups of 4-5 cm increments to make mAs adjustments simpler.. initial phantom images-uses mAs for the AP lumbar spine-measure pt thickness. kVp is selected from the kVp chart and required mAs is estimated based on previous experience. 2. Select optimal phantom image-do not alter kVp from the value shown for a part thickness, but instead determine the appropriate mAs.
