Background: Computed tomography (CT) examinations account for a significant portion of individuals' increasing exposure to medical radiation. Automatic exposure control (AEC) was introduced in CT scanners to decrease patient doses while maintaining appropriate image quality.

av A Ludvigsson — användning av AEC. Metod: Ett fantom undersöktes i CT med olika positioner: 6cm och 3cm under isocenter och 3cm och 5.7cm över. Bildförstoring

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. introduction of faster multidetector CT scanners, various techniques have been developed to reduce the radiation dose to the patient; one method is automatic exposure control (AEC).

Its function is to automatically terminate exposure when a preset amount of radiation has been detected.

Higher noise index or SD is recommended for larger patients. 32 This philosophy is implemented in the AEC in Siemens CT equipment (Siemens Medical Solutions, Malvern, Pennsylvania) and the tube current is changed less for large and small patients than it would be if constant image noise was the aim. 15 Recently, GE (GE Healthcare, Waukesha
