Abstract
A block diagram representation of the circuitry is shown in Figures 1 and 2. Figure 1 shows the basic elements of an automatic exposure control with an ionization chamber as a detector. (Phototubes may also be used in place of ion chambers.) Figure 2 shows a typical automatic exposure control system with several ionization chamber detectors, and a photospot detector. It also shows an optional tomographic exposure control with current feedback and kVp servo compensation.
