Automatic Exposure Control in Multidetector-row CT

Part of the Medical Radiology book series (MEDRAD)


Automatic exposure control (AEC) is one of the most important aspects of radiation dose and image quality optimization for CT scanning. It is important to use this technique appropriately in order to obtain CT examinations with required image quality and/or radiation dose levels as improper use can lead to much lower or much higher radiation doses to patients undergoing CT examinations. There is similarity in basic principle behind different AEC techniques across different CT vendors but there are considerable differences between how the techniques are applied on platforms of different CT vendors. This chapter discusses various techniques of AEC available for use on clinical CT equipments.
