Proper density with AEC is achieved when:
all three photocells are preselected, the back up timer is reached, and the exposure terminates
the back up timer is reached and the exposure terminates
all 3 photocells are preselected
the anatomy sufficiently covers the chamber selected
the anatomy sufficiently covers the chamber selected
Rationale: AEC when selected are designed to ensure proper density for a part is achieved. kVp is selected along with the cell according to part coverage is selected. The exposure is terminated when optimal density is reached. Proper positioning and selection of the corresponding photocells are important to achieving wanted density.
