AEC has become a standard dose reduction and image quality tool and is offered in various forms by all major CT manufacturers. Effective use of this important dose management tool requires an understanding of the AEC system implemented by the manufacturer. The four major AEC schemes are summarized in Table I, according to manufacturer.

Several studies have shown a significant patient dose reduction without compromising image quality when AEC systems are used in CT [3,5,10].

AEC systems make use of different types of control, including patient-size AEC, z-axis AEC, rotational or angular AEC, or a combination of two or more of these types. I. INTRODUCTION.

Since the CT AEC system determines the appropriate dose for an examina - tion on a patient-by-patient basis, the AEC system is a major component in the determination of patient dose and image quality in clinical CT scanning. It is therefore important to test the AEC (Architecture, Engineering and Construction) cancel.
