Although many current CT scanners incorporate CT-AEC, performance evaluation is not standardized. This study evaluates the performance of the latest CT-AEC of each manufacturer with the aim of establishing a standard CT-AEC performance evaluation method. The design of the phantoms was based upon the operation characteristics of different CT-AECs.

CTAEC-50 (Computed Tomography Automatic Exposure Control) phantom is used for constancy testing of CT AEC systems. CTAEC-50 includes: 6x PMMA ellipses of 50mm thickness (different height and width so that they can be re-configured into any order) 2 …

The effect of patient centering on AEC function was evaluated by scanning an acrylic phantom at a variety of different off-center positions in three different CT Conclusion: The AEC systems available in modern CT scanners can contribute to a significant reduction in radiation exposure to the patient and the image noise Jul 7, 2016 PDF | Automatic exposure control (AEC) systems for CT scanners are now available from all the major scanner manufacturers. These systems Investigation of the characteristics of Automatic Exposure Control (AEC) of a Computed Tomography (CT) scanner by utilising cylindrical and anthropomorphic Jul 8, 2016 The usefulness of this phantom setup for CT AEC testing was also demonstrated by Iball in 2011. For the past 45 months our Medical Physics Sep 4, 2008 Abbreviations: ACS = automatic current selection, AEC = automatic exposure control, DLP = dose-length product. RadioGraphics 2008; 28:1451– Oct 15, 2015 Once the scan begins, AEC automates the adjustment of tube current (mA) along the way to optimize dose even further. The goal of AEC is to Get directions, reviews and information for Aec Inc in New Haven, CT.

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. AEC Systems for GE CT Scanners: AutomA vs. SmartmA. By: David Harns on May 23, 2014 9:30:00 AM CT. You probably already know that automatic exposure control (AEC) is an excellent way to help reduce the radiation dose to the patients you scan with your … Computed tomography (CT) automatic exposure control (AEC) systems were first introduced in the mid‐1990s, but have become an integral part of all modern CT … Thus, CT manufacturers developed automatic exposure compensation (AEC) methods for CT, which typically involve tube current (mA) modulation.
