The Importance of Patient Positioning in Radiography When Utilising Automatic Exposure Control

Statistically significant differences in dose were commonly discovered for mis-positioning beyond 1-2 cm, which will likely occur within the clinical environment. Such variation in dose and signal-to-noise ratio identifies potential impacts to image quality and dose burdens to patients. The results highlight the need for careful consideration when using the AEC and the requirement for accurate positioning technique by the radiographer.
