Book Description
This book addresses the most relevant aspects of radiation oncology in terms of technical integrity, dose parameters, machine and software specifications, as well as regulatory requirements. Radiation oncology is a unique field that combines physics and biology. As a result, it has not only a clinical aspect, but also a physics aspect and biology aspect, all three of which are inter-related and critical to optimal radiation treatment planning. In addition, radiation oncology involves a host of machines/software. One needs to have a firm command of these machines and their specifications to deliver comprehensive treatment. However, this information is not readily available, which poses serious challenges for students learning the planning aspect of radiation therapy. In response, this book compiles these relevant aspects in a single source. Radiation oncology is a dynamic field, and is continuously evolving. However, tracking down the latest findings is both difficult and time-consuming. Consequently, the book also comprehensively covers the most important trials. Offering an essential ready reference work, it represents a value asset for all radiation oncology practitioners, trainees and students.

Book Description
Radiation dosimetry has made great progress in the last decade, mainly because radiation therapy is much more widely used. Since the first edition, many new developments have been made in the basic methods for dosimetry, i.e. ionization chambers, TLD, chemical dosimeters, and photographic films. Radiation Dosimetry: Instrumentation and Methods, Second Edition brings to the reader these latest developments. Written at a high level for medical physicists, engineers, and advanced dosimetrists, it concentrates only on evolvement during the last decade, relying on the first edition to provide the basics.

Book Description
During a radiotherapy treatment, skin of the patient is always exposed to the radiation; as a consequence late effects can be appear. Therefore, dose values in this region may be of interest for clinical evaluation and investigation of those undesirable effects. However, surface dose is not intuitive and is difficult to measure and calculate; the parameters, which modify it are not always the same and each one are dependent to the others. The aim of this project is to quantify absorbed dose in the build-up region and near to the skin approximately between 0 mm - 1 mm using two methods. One of them, an analytical calculation using Monte Carlo simulations; and the other an experimental approach using an extrapolation chamber. Monte Carlo simulations are performed with the PENELOPE package of subroutines for 6MV and 15MV photon beams. Experimental setup consists in the use of an extrapolation chamber (PTW model 23392), considered the most suitable instrument to measure absorbed dose in the build-up region, but its not commonly available in the hospitals because its use is not practical. The chamber was adapted for its use in clinical environments in a previous work, then for this work the measurement process is easier and results with high level of accuracy can be obtained. In this way, EC (extrapolation chamber) measurements served as the gold standard in our study to validate the Monte Carlo simulations and also with results reported by previous studies. As a result, we found that simulation outcomes are in good agreement with experimental data.

Book Description
This Code of Practice, which has also been endorsed by WHO, PAHO and ESTRO, fulfils the need for a systematic and internationally unified approach to the calibration of ionization chambers in terms of absorbed dose to water and to the use of these detectors in determining the absorbed dose to water for the radiation beams used in radiotherapy. It provides a methodology for the determination of absorbed dose to water in the low, medium and high energy photon beams, electron beams, proton beams and heavy ion beams used for external radiation therapy.

Book Description
Described in this book are features of various techniques that are in use for the quantitative measurement of radiation doses. The authors who are working specialists in different parts of the world have attempted to introduce these techniques not only in a comprehensive manner but, also, review the current state of art as well and explain applications.
