Main description:

This book focuses on an area often overlooked at an elementary level. As modern medicine develops, it brings forth important changes in the physics component. This updated edition enables an understanding of physics' role in medicine as well as the most current technologies. It continues to be an invaluable resource for a range of readers, from undergraduates to medical professionals. The author provides explanations of necessary scientific background, detailed descriptions and diagrams, and case studies in each chapter. A solutions manual and extended lecturer support online aid professors in teaching the course and staying up-to-date on any new developments.
