ABSTRACT
Imaging has probably been the most important driving force for the development of brachytherapy treatments during the past several years. rough 3D imaging, brachytherapy became a highly accurate and reliable treatment option in radiotherapy. Tumor volumes and organs at risk (OARs) are visibly good in many cases, and applicators can be reconstructed in three dimensions. Moreover, intraoperative techniques, in particular, transrectal ultrasound (US) for prostate, are nowadays standard in most clinics. is chapter discusses the possibilities and limitations of various imaging methods for brachytherapy. It
contains a short physical explanation of each methodology followed by a description of the practical use in dierent body sites.
