Question

1 multiple choice 1 point the single function of an aec is to eliminate the need to set kvp. ma. time. all of the above. 2 multiple choice 1 point when using an aec, the radiographer loses control of distance. ma. kvp. mas.

Explanation:

1. Automatic Exposure Control (AEC) is designed to automatically adjust the exposure factors to achieve a consistent image density. It eliminates the need to manually set mAs (which is a product of mA and time), not kVp or distance. So for the first - question, none of the options are correct as AEC mainly relates to mAs adjustment. For the second question, when using AEC, the radiographer loses control of mAs as the AEC system determines the appropriate mAs value for the desired exposure.

Answer:

1. None of the above
2. mAs
