Imaging is a key part of clinical practice. To maximise the potential benefit to their patients, dentists need to have an understanding of how imaging systems work. In the 21st century, we are faced with major technological developments in radiology, of which many dentists will be unfamiliar. This book aims to address these challenges by providing a comprehensive introduction to state-of-the-art dental imaging, in particular to the complexities of digital radiology and the advanced techniques available for cross-sectional imaging.
