Planning is a critical stage of radiotherapy. Careful consideration of the complex variables involved & critical assessment of the techniques available are fundamental to good & effective practice. First published in 1985 Practical Radiotherapy Planning has over three editions established itself as the popular choice for the trainee raditation oncologist & radiographer providing the nuts & bolts of planning in a practical & accessible manner. This fourth edition encompasses a wealth of new material reflecting the radical change in the practice of radiotherapy in recent years. The information contained within the introductory chapters has been expanded & brought up to date & a new chapter on patient management has been added. CT stimulators MLC shieldings & dose profiles principles of IMRT & use of MRI PET & ultrasound are all included amongst other new developments in this field. The aim of the book remains unchanged. Complexity of treatment planning has increased greatly but the fourth edition continues to emphasise underlying principles of treatment that can be applied for conventional conformal & novel treatments taking into account advances in imaging & treatment delivery.
