Brachytherapy delivers a highly localized dose to a target region using radionuclides implanted in or very near to the tumor. This book provides a complete overview of the field and covers related delivery modalities such as electronic brachytherapy. Along with exploring new clinical protocols, it discusses major advances under development, including imaging, robotics, strategies for improved dosimetry, Monte Carlo-based dose calculation, and optimization. The first part of the text offers a detailed understanding of the underlying physics, design, and implementation of the techniques. The second part provides a practical guide for practitioners--Provided by publisher.
