AEC chamber

Automatic Exposure Control

The AEC chamber is an accessory for X-Ray systems (projection radiography).

The AEC chamber provides a signal proportional to the image receptor dose, enabling X-Ray imaging with optimal diagnostic image quality with minimal patient radiation exposure.

The AEC chambers are air-filled parallel-plate ionization chambers with typically one or three independent sensor fields.

The Ionisation Chambers are used as sensor elements for automatic X-Ray exposure control units. They comprise air-filled parallel chambers with 1 or 3 measuring fields, coupled with an amplifier and a field selector.

The current generated in the sensor fields by the X-Rays will be amplified, digitized and fed to the automatic exposure controller. The AEC supplies the cut-off signal to the generator, and thereby ensures an optimal and reproducible image quality, independent of the radiation quality, object density, and other factors.
