Dr. Khan’s classic textbook on radiation oncology physics is now in its thoroughly revised and updated Fourth Edition. It provides the entire radiation therapy team—radiation oncologists, medical physicists, dosimetrists, and radiation therapists—with a thorough understanding of the physics and practical clinical applications of advanced radiation therapy technologies, including 3D-CRT, stereotactic radiotherapy, HDR, IMRT, IGRT, and proton beam therapy. These technologies are discussed along with the physical concepts underlying treatment planning, treatment delivery, and dosimetry.

This Fourth Edition includes brand-new chapters on image-guided radiation therapy (IGRT) and proton beam therapy. Other chapters have been revised to incorporate the most recent developments in the field. This edition also features more than 100 full-color illustrations throughout.

A companion Website will offer the fully searchable text and an image bank.

Key Features

• NEW! New chapter on image-guided radiation therapy (IGRT) details physics and practical applications of this cutting-edge technology for conformal radiation therapy. The chapter describes the principles and use of on-board imagers and tumor tracking devices, with discussion of image quality, advantages, and limitations of each modality.
• NEW! New chapter on proton beam therapy. This new radiation therapy modality uses high-energy proton beams to treat tumors with a high degree of conformality, concentrating dose to the tumor but sparing surrounding critical structures and reducing integral dose to normal tissues in the path of the beam. This technology has become established enough to be included in the current edition. The physics of proton beam generation, delivery, and beam characteristics are discussed along with clinical applications, dosimetry, treatment planning algorithms, and quality assurance.
• NEW! Chapters significantly revised to detail new developments over the past eight years, including cyberknife technology, tomotherapy, and intensity modulated radiation therapy (IMRT)
• NEW! Now in full color, with 148 new full-color images
• NEW! Illustrations overhauled to reflect current practice and depict new procedures added
• NEW! Boxed Key Points added at the end of each chapter
