Centering Accuracy
AEC failure often results from poor centering. Off centering activates the wrong chamber and produces inconsistent exposures. Proper alignment reduces repeat imaging. Centering is essential for AEC reliability.
Field Size Awareness
Excessive collimation can deactivate AEC chambers. Maintaining adequate field size ensures proper chamber function. Awareness of field limits improves consistency. Field control supports accurate exposure.
Prosthetic Considerations
Metal prosthetics can trigger AEC overexposure. Adjusting chamber selection prevents excessive radiation. Awareness of prosthetics improves technique. Proper planning reduces errors.
Backup Techniques
When AEC is unreliable manual techniques provide consistent results. Monitoring exposure index ensures proper detector response. Backup methods improve workflow stability. Technique flexibility is essential.
