The purpose of this textbook is not only to present the subjects of physics and imaging within the same cover but also to link them together so that the student understands how the subjects relate to each other and to clinical practice. This textbook follows the ASRT-recommended curriculum and covers the content specifications of the ARRT radiography exam, making it easier for faculty to ensure appropriate coverage and adequate assessment of content mastery. But equally important, it provides the knowledge and information essential to a competent radiographer. This third edition continues to provide up-to-date digital information as the primary imaging modality used today.

This textbook was written by radiographers for radiographers in a simple, straightforward, but level-appropriate manner. It is a comprehensive radiologic physics and imaging text that focuses on what the radiographer needs to know and understand to safely and competently perform radiographic examinations. To achieve this, the following are some of the books unique features:

• Each chapter begins with a rationale for studying the content of that chapter, addressing the often-asked question Why do we need to know this? The introduction to below is an example.
