Part I MRI for Planning: Basics of MRI and Radiotherapy -- Patient set-up & positioning -- Guidelines for MRI acquisition -- Quality Assurance -- Clinical Sites -- Part II MRI during treatment: Functional imaging& response assessment -- Adaptive radiotherapy -- Part III MR-only Radiotherapy: Challenges & requirements -- Atlas based methods -- Direct conversion -- Part IV Real-time guidance: First clinical results -- MRI-Linac systems -- Proton therapy -- Part V MR in RT 2017: Selection of papers from 5th International MR in RT Symposium.

This book provides, for the first time, a unified approach to the application of MRI in radiotherapy that incorporates both a physics and a clinical perspective. Readers will find detailed information and guidance on the role of MRI in all aspects of treatment, from dose planning, with or without CT, through to response assessment. Extensive coverage is devoted to the latest technological developments and emerging options. These include hybrid MRI treatment systems, such as MRI-Linac and proton-guided systems, which are ushering in an era of real-time MRI guidance. The past decade has witnessed an unprecedented rise in the use of MRI in the radiation treatment of cancer. The development of highly conformal dose delivery techniques has led to a growing need to harness advanced imaging for patient treatment. With its flexible soft tissue contrast and ability to acquire functional information, MRI offers advantages at all stages of treatment. In documenting the state of the art in the field, this book will be of value to a wide range of professionals. The authors are international experts drawn from the scientific committee of the 2017 MR in RT symposium and the faculty of the ESTRO teaching course on imaging for physicists.
