Best practice guidelines for the use of automatic exposure control include all of the following except
1)set the optimum kV for the body part.
2)set the backup timer to 150% to 200% of the expected manual exposure.
3)set the highest mA station for the focal spot size needed.
4)wide collimation will ensure IR coverage.

The best practice guidelines for the use of automatic exposure control include setting the backup timer to 150% to 200% of the expected manual exposure to avoid overexposure, setting the highest mA station for the focal spot size needed to ensure optimal image quality, and collimating appropriately to ensure efficient use of radiation and minimize patient dose. However, it is not necessary to set the optimum kV for the body part when using automatic exposure control, as this is automatically adjusted by the system based on the thickness and density of the body part being imaged.
