Proton Therapy Physics, Second Edition


Book Description

Expanding on the highly successful first edition, this second edition of Proton Therapy Physics has been completely restructured and updated throughout, and includes several new chapters. Suitable for both newcomers in medical physics and more seasoned specialists in radiation oncology, this book provides an in-depth overview of the physics of this radiation therapy modality, eliminating the need to dig through information scattered across medical physics literature. After tracing the history of proton therapy, the book explores the atomic and nuclear physics background necessary for understanding proton interactions with tissue. The text then covers dosimetry, including beam delivery, shielding aspects, computer simulations, detector systems and measuring techniques for reference dosimetry. Important for daily operations, acceptance testing, commissioning, quality assurance and monitor unit calibrations are outlined. The book moves on to discussions of treatment planning for single- and multiple-field uniform doses, dose calculation concepts and algorithms, and precision and uncertainties for nonmoving and moving targets. Imaging for treatment guidance as well as treatment monitoring is outlined. Finally, the biological implications of using protons from a physics perspective are discussed. This book is an ideal practical guide for physicians, dosimetrists, radiation therapists, and physicists who already have some experience in radiation oncology. It is also an invaluable reference for graduate students in medical physics programs, physicians in their last year of medical school or residency, and those considering a career in medical physics. Features: Updated with the latest technologies and methods in the field, covering all delivery methods of proton therapy, including beam scanning and passive scattering Discusses clinical aspects, such as treatment planning and quality assurance Offers insight on the past, present, and future of proton therapy from a physics perspective




Shielding Techniques for Radiation Oncology Facilities


Book Description

A textbook for a senior or graduate course in medical or health physics. Students are assumed to be familiar with the radiation- producing devices used in radiation oncology. The second volume corrects some errors detected in the 1998 first, and adds discussions of intensity modulated radiation therapy, CT room design, the design of direct shielded doors, and other topics.

Proton Radiotherapy Accelerators


Book Description

Hadronic radiotherapy uses particle beams to treat tumors located near critical body structures and tumors that respond poorly to conventional photon and electron beam radiotherapy. Initial research in hadronic radiotherapy was performed using accelerators built for physics research. The good results of the proton and ion therapy programs have enhanced the tendency to use protontherapy as a routine method. There are about 20 working protontherapy facilities (first, second and third generation) and more than 30 centers are planned.This book presents the first comprehensive overview of the field with a discussion on the fundamental basis of particle physics and radiobiology, as well as review of clinical and technical specifications and designs for proton radiotherapy. In particular, the current designs of proton and heavy ion accelerators, beam delivery systems, gantries, beam monitoring and dosimetry systems, control and safety systems, patient positioning and immobilization devices, and ancillary treatment facilities are widely discussed.










Handbook of Spallation Research


Book Description

This detailed and comprehensive reference to spallation -- from the foundations to the latest applications is the only work of its kind and is written by two internationally renowned researchers. Clearly divided into three parts, it begins with the basic principles, while the second part describes the proton-nucleus and proton-matter experiments so-called thin and thick target experiments in terms of secondary particle production as hadrons, pions, muons, photons, electrons, light and intermediate masses, isotope production, heating and energy deposition and materials damage. Many of the experiments are associated with studies, investigations and the construction of spallation neutron sources since 1975 with emphasis on the most recent developments. The final part on technology and applications describes the various engineering problems associated with high intensity neutron spallation sources, ATW's, the needed accelerator systems, material and neutron issues, and high energy neutron source shielding aspects. A must-have for engineers and physicists working in or entering this field.




Proton Therapy and Radiosurgery


Book Description

The book is divided into two parts: Part I deals with the relevant physics and planning algorithms of protons (H Breuer) and Part II with the radiobiology, radiopathology and clinical outcomes of proton therapy and a comparison of proton therapy versus photon therapy (BJ Smit). Protons can be used for radiosurgery and general radio therapy. Since proton therapy was first proposed in 1946 by Wilson, about sixteen facilities have been built globally. Only a very few of these have isocentric beam delivery systems so that proton therapy is really only now in a position to be compared directly by means of randomised clinical trials, with modern photon radiotherapy therapy sys tems, both for radiosurgery and for general fractionated radiotherapy. Three-dimensional proton planning computer systems with image fusion (image of computerised tomography (CT), magnetic resonance registration) capabilities imaging (MRI), stereotactic angiograms and perhaps positron emission tomography (PET) are essential for accurate proton therapy planning. New planning systems for spot scanning are under development. Many of the older comparisons of the advantageous dose distributions for protons were made with parallel opposing or multiple co-planar field arrangements, which are now largely obsolete. New comparative plans are necessary once more because of the very rapid progress in 3-D conformal planning with photons. New cost-benefit analy ses may be needed. Low energy (about 70 MeV) proton therapy is eminently suitable for the treatment of eye tumours and has firmly established itself as very useful in this regard.
