Klappentext Image-guided radiation treatment (IGRT) is rapidly becoming the standard in external-beam radiation therapy. Its advantages include greater precision! reduced likelihood of positioning errors! and online correction of motion errors. This volume provides a cutting-edge overview of the latest IGRT technology and systems! including an historical perspective! discussion of future directions! and insights from the firsthand experiences of the expert authors. Each chapter discusses the geometry of the imaging and treatment system! relevant imaging principles and algorithms! treatment principles! image fidelity (scatter! spatial! and contrast resolution)! and clinical applications. Zusammenfassung Image-Guided Radiation Therapy presents key image-guided radiation treatment (IGRT) technologies for external beam radiotherapy. The book explores the decades-long technological developments that have occurred in the realm of image-guided conformal, customized radiation treatment. Expert authors, all of whom have actively participated in the development or implementation of IGRT, imaging, and enabling technologies, share their first-hand experiences on the science, clinical uses, and impact of these technologies. They describe kilovoltage and megavoltage imaging as well as radiological, ultrasound, and optical technologies for determining and validating target and patient positioning. The book examines how anatomical and biological imaging using CT and PET has contributed to the understanding of target volume boundaries and biological behavior. It also explores such innovations as 4D PET/CT and digital tomosynthesis. Advancing patient care, this book focuses on a wealth of hybrid IGRT technologies and devices for coupled imaging and treatment inside the radiation treatment room. It thoroughly covers the modalities, software tools, and imaging treatment geometries that constitute IGRT. Inhaltsverzeichnis Optical and Remote Monitoring IGRT. Ultrasound-Guided Radiation Therapy.
