Abstract

Production of a diagnostic quality radiograph requires the delivery of a predetermined amount of x-radiation to the film-screen combination. Variations in patient thickness and absorption make it difficult to predict the x-ray exposure values necessary to produce an incident beam which will yield the predetermined transmitted amount of radiation at the film-screen. Automatic exposure control devices largely solve this problem when properly designed. Design problems facing the automatic exposure control designer are discussed along with a summary of the characteristics of a diagnostic quality radiographic image.
