Which statement correctly describes anatomical alignment with AEC?

The correct statement about anatomical alignment with Automatic Exposure Control (AEC) is that the patient must be positioned in front of the active detectors selected. AEC systems are designed to automatically adjust the exposure time based on the amount of radiation needed to achieve a proper image quality, which is influenced by the anatomy being imaged. For the AEC to function correctly, the anatomical area of interest must be aligned with the detector that is activated.

This alignment ensures that the radiation exposure is accurately measured based on the density of the tissues in that specific area, allowing for optimal image quality while minimizing radiation dose. If the patient is not properly positioned in front of the active detectors, the AEC may either overexpose or underexpose the image, compromising diagnostic effectiveness.

Thus, proper positioning relative to the active detectors is crucial for achieving the appropriate exposure settings, making this statement a key principle in utilizing AEC effectively during imaging procedures.
