Automatic exposure devices provide a diagnostic quality radiograph when the
A)anatomy of interest is positioned directly above the appropriate ionization chambers.
B)proper time is set.
C)correct focal spot is selected.
D)beam filtration is minimum.

Question

Quizplus · Accepted Answer

Automatic exposure devices rely on ionization chambers located under the anatomy of interest to measure the thickness of the body part and adjust the exposure time accordingly. Therefore, positioning the anatomy of interest directly above the appropriate ionization chambers is essential to ensure a diagnostic quality radiograph. The other options (B, C, and D) are also important factors in obtaining a quality radiograph, but without proper positioning over the ionization chambers, the exposure may not be appropriate for the specific anatomy being imaged.
