Detector Coverage
AEC chambers require full coverage of the anatomy to function correctly. Incomplete coverage causes underexposure and noise. Proper centering ensures accurate chamber activation. Coverage awareness improves consistency.
Chamber Selection
Selecting the correct chamber improves exposure accuracy. Using the wrong chamber can overexpose or underexpose the image. Chamber choice must match the anatomy. Proper selection enhances diagnostic quality.
Collimation Effects
Tight collimation can deactivate AEC chambers if the field becomes too small. This leads to incorrect exposure index values. Awareness of field size prevents errors. Collimation must be balanced with AEC needs.
Patient Thickness
AEC adjusts exposure based on patient thickness. Extreme thickness variations require manual technique adjustments. Monitoring exposure index ensures proper detector response. Thickness awareness supports accurate imaging.
