An x-ray image receptor, containing an anti-scatter grid and three AEC regions (represented by dark grey circles and square) These regions represent anatomical areas, e.g. lungs, spine. They can be selected individually, or all at once depending on the need. Automatic Exposure Control (AEC) is an X-ray exposure termination
Fish bone pierced in the upper esophagus. Right image without contrast medium, left image during swallowing with contrast medium. To obtain an image with any type of image detector the part of the patient to be X-rayed is placed between the X-ray source and the image receptor to produce a shadow of the internal structure of that particular part of the body.
AEC may refer to: Organizations ... African Energy Chamber; Alaska Engineering Commission; ASEAN Economic Community; Assessment and Evaluation Commission, ...
The AEC also began a program of regular nuclear weapons testing, both in the faraway Pacific Proving Grounds and at the Nevada Test Site in the western United States. While the AEC also supported much basic research, the vast majority of its early budget was devoted to nuclear weapons development and production. [citation needed]
An accelerated climate simulation chamber was built that applied varying weather conditions to insulation to test its efficacy and durability faster than real time. [22] Materials research into heat resistant ceramics for use in truck and high-tech car engines was performed, building upon the materials research that began in the nuclear ...
While standard practice MFG testing requires careful definition, monitoring and control of temperature, humidity, gaseous pollutant concentrations, volume exchange rate and airflow rate, there is considerable potential for variations in mass flow, environmental mixing and gradients in the chambers used.
AEC in particular is commonly used to refer to echo cancelers in general, regardless of whether they were intended for acoustic echo, line echo, or both. Although echo suppressors and echo cancellers have similar goals—preventing a speaking individual from hearing an echo of their own voice—the methods they use are different:
The Automotive Electronics Council (AEC) is an organization originally established in the 1990s by Chrysler, Ford, and GM for the purpose of establishing common part-qualification and quality-system standards. The AEC Component Technical Committee is the standardization body for establishing standards for reliable, high quality electronic ...
