which radiographic projection require the use of automatic exposure control (AEC/AED)?
when do you use each chamber? e.g the middle chanmber is used for the spine but what else? and the lateral chambers can be used for abdomin radiography but what else? is the central chamber used for lateral abdomin or do you not use AEC for this projection? I'm very confused!!

Automatic Exposure Control (AEC) is an X-ray exposure termination device. A medical radiography x-ray exposure is always initiated by a human operator. X-ray termination is done by the same human operator or an exposure control device such as an electronic timer or an AEC device, which ever comes first. The intention of the AEC termination device is to provide consistent x-ray film appearance.
