The main objective of this book is to provide radiation oncologists with a clear up-to-date
guide to tumor delineation and contouring of organs at risk. With this in mind a detailed
overview of recent advances in imaging for radiation treatment planning is presented. Novel
concepts for target volume delineation are explained taking into account the innovations in
imaging technology. Special attention is paid to the role of the newer imaging modalities such
as positron emission tomography and diffusion and perfusion magnetic resonance imaging. All of
the most important tumor entities treated with radiation therapy are covered in the book. Each
chapter is devoted to a particular tumor type and has been written by a recognized expert in
that topic.
