Mastering Automatic Exposure Control (AEC) in X-ray Machines

It eliminates the need to set the mA and kVp values

It eliminates the need to know in advance how much exposure time a radiograph will require (correct)

It eliminates the need for a sensing device under the x-ray table

It eliminates the need for a rotor switch

To detect the position of the Bucky

To control the exposure switch

To terminate the exposure time when a certain quantity of radiation has been detected at the image receptor (correct)

To set the mA and kVp values

To initiate the exposure by continuing to hold the switch

To terminate the exposure time

To spin the rotating anode and apply heat to the filament to create electrons (correct)

To detect when the tube is ready for an exposure
