This publication is intended to support those working in the field of diagnostic radiology dosimetry, both in standards laboratories involved in the calibration of dosimeters and those in clinical centres and hospitals where patient dosimetry and quality assurance measurements are of vital concern. This code of practice covers diverse dosimetric situations corresponding to the range of examinations found clinically, and includes guidance on dosimetry for general radiography, fluoroscopy, mammography, computed tomography and dental radiography. The material is presented in a practical way with guidance worksheets and examples of calculations. A set of appendices is also included with background and detailed discussion of important aspects of diagnostic radiology dosimetry.
This publication is aimed at students and teachers involved in programmes that train medical physicists for work in diagnostic radiology. It provides a comprehensive overview of the basic medical physics knowledge required in the form of a syllabus for the practice of modern diagnostic radiology. This makes it particularly useful for graduate students and residents in medical physics programmes. The material presented in the publication has been endorsed by the major international organizations and is the foundation for academic and clinical courses in both diagnostic radiology physics and in emerging areas such as imaging in radiotherapy.
This completely updated second edition of Radiation Exposure and Image Quality in X-ray Diagnostic Radiology provides the reader with detailed guidance on the optimization of radiological imaging. The basic physical principles of diagnostic radiology are first presented in detail, and their application to clinical problems is then carefully explored. The final section is a supplement containing tables of data and graphical depictions of X-ray spectra, interaction coefficients, characteristics of X-ray beams, and other aspects relevant to patient dose calculations. In addition, a complementary CD-ROM contains a user-friendly Excel file database covering these aspects that can be used in the reader’s own programs. This book will be an invaluable aid to medical physicists when performing calculations relating to patient dose and image quality, and will also prove useful for diagnostic radiologists and engineers.
This book explores the physics of CT dosimetry and provides practical guidance on best practice for medical researchers and practitioners. A rigorous description of the basic physics of CT dosimetry is presented and illustrates flaws of the current methodology. It also contains helpful (and rigorous) shortcuts to reduce the measurement workload for medical physicists. The mathematical rigor is accompanied by easily-understood physical explanations and numerous illustrative figures. Features: Authored by a recognised expert in the field and award-winning teacher Includes derivations for tube current modulation and variable pitch as well as stationary table techniques Explores abnormalities present in dose-tracking software based on CTDI and presents methods to correct them
Physics for Diagnostic Radiology, Second Edition is a complete course for radiologists studying for the FRCR part one exam and for physicists and radiographers on specialized graduate courses in diagnostic radiology. It follows the guidelines issued by the European Association of Radiology for training. A comprehensive, compact primer, its analytical approach deals in a logical order with the wide range of imaging techniques available and explains how to use imaging equipment. It includes the background physics necessary to understand the production of digitized images, nuclear medicine, and magnetic resonance imaging.
The first edition of this book was published in 2000 and it has become the standard for shielding design in the UK. The second edition is designed to be a compendium of information for radiation protection physicists involved in specification of shielding requirements for X-Ray facilities.
Fosters a thorough understand of radiation dosimetry concepts: detailed solutions to the exercises in the textbook Fundamentals of Ionizing Radiation Dosimetry!
The International Basic Safety Standards for Protection against Ionizing Radiation and for the Safety of Radiation Sources (BSS), jointly sponsored, inter alia, by the IAEA, ILO, WHO and PAHO, establish requirements on the legal persons responsible for designing, running and decommissioning practices involving ionizing radiation. These requirements are basic and general in nature. This report is intended to be of assistance to both regulators and users of radiation sources in diagnostic radiology and interventional procedures using X rays in applying the BSS to this practice. Regulators will find it useful for reviewing applications for authorization and for the inspection of the practice. Users of radiation in radiology may follow the guidance provided in order to comply with BSS requirements or equivalent national requirements. Experts recruited on IAEA missions to advise on the implementation of the BSS for the practice of diagnostic radiology and interventional procedures using X rays are expected to use this regulatory guidance report rather than their own national regulations and guidance. --Publisher's description.
Whenever a diagnostic or interventional X-ray examination of a pregnant patient is considered to be necessary, conceptus dose estimation is an essential step in assessing the radiogenic risks to the unborn child. Accurate estimation of embryo/fetus radiation dose is also needed after accidental exposure of a pregnant patient from an X-ray procedure. The exposure of pregnant patients to medical X-rays is often a complex case and involves emotionally sensitive issues for both prospective parents and physicians. Conceptus dose assessment is not always easy. Medical physicists should be able to assess conceptus doses and risks from diagnostic and interventional procedures and also to place the risk in a perspective from which an informed decision can be made. Pregnant medical professionals working with radiation have many misconceptions about the risks of ionizing radiation on the unborn child. Medical radiation workers of childbearing age should be aware that careful planning and dose optimization of examinations can address their concerns and permit, in the vast majority of cases, safe performance of procedures. Pediatric patients requiring diagnostic and interventional procedures are exposed to diagnostic and interventional X-rays. Pediatric patients are more sensitive to radiation than adults and, for this reason, accurate assessment of doses and risks is needed in these cases. Medical physicists should be able to assess paediatric doses and risks from diagnostic and interventional procedures. Several techniques and tools have been developed for dose optimization of radiographic, fluoroscopic, computed tomography and fluoroscopically-guided interventional pediatric procedures. The scan parameters should be adjusted for patient size and body region. Part of Series in Physics and Engineering in Medicine and Biology.
This book on radiochromic film covers the basic principles with a focus on the latest methods and applications in radiation dosimetry. It reflects advances in digital imaging and scanning equipment and modern uses of radiochromic films in diagnostic x-rays, brachytherapy, radiosurgery, and other emerging techniques.
