Course Description
Diagnostic radiography is one of the most often utilized imaging methods in medicine. Diagnostic X-rays are produced when highly energetic electrons interact with matter and convert their kinetic energy into electromagnetic radiation. To reach this stage of X-ray production, a diagnostic radiographic system (DRS) must have key operational internal and external components in place, each with a role to play in the final production of X-rays. In addition, many technical parameters of X-ray production equipment affect the magnitude and shape of the X-ray spectrum that's produced. X-ray quantity and shape are also affected by the atomic number of the anode material, tube potential, voltage waveform (generator type), and tube filtration (inherent and added). Understanding the basics of DRSs the equipment and its components is the foundation for radiologic technologists' (RTs') to be able to successfully complete high-quality imaging studies, with the goal of achieving accurate patient diagnosis and treatment. This course will explain the key physical components that make up a DRS, their function, circuitry, and interaction with each other. Reviews of the science, mathematics, and physics that make X-ray production possible will be explained. Key internal and external DRS components and the creation of X-ray ionizing radiation needed to form a diagnostic image will be explained and discussed in detail.

Learning Objectives
After reviewing the content, participants should be able to:

• EXPLAIN the history, evolution, various components, and concepts of the X-ray tube and its connection to the main circuit of a diagnostic radiographic system (DRS).
• OUTLINE the types of transformers, rectifiers, physics concepts, associated circuitry, radiographic exposure timers, and processes that generate X-rays in a DRS.
• RECALL the basic principles of electricity, physics, terminology, and various components that make up X-ray generators used in diagnostic radiographic imaging suites.
• RECALL the types of automatic exposure control devices and their operation, functionality, and limitations.
• IDENTIFY the heat units generated by an X-ray tube and EXPLAIN rating charts and warm-up protocols and techniques to maintain both patient and radiologic technologist safety.
• DIFFERENTIATE internal and external components that make-up a diagnostic radiography imaging suite, including the built-in grids, table, upright wall Bucky, and equipment support columns.
