The purpose of this chapter is to present a general overview of the digital radiographic imaging systems used in diagnostic radiology, by describing briefly, the general system components of each of the modalities in an effort to lay the foundations needed for a good understanding of how each component works to create images and protect not only patients but technologists as well. The more technical details will be reviewed in later chapters on each of the modalities. First, it is important to review the essential principles of film‐screen radiography (FSR) in order to fully understand the rationale for the emergence of digital imaging modalities.
