Guidance On The Measurement And Use Of Emf And Emc

Physicists and engineers who work in healthcare are finding that they need to know more and more about electromagnetic fields and electromagnetic compatibility, in order to assess occupational exposure, to design equipment that works without suffering from or causing interference, and to comply with an increasingly complex legislative framework. This report will help them do this. Starting with an overview of the relevant directives and guidelines, the publication next gives practical advice on how to design medical equipment for EMC, and describes the types of equipment that are available for measuring electric and magnetic fields. There are then more specific chapters on RF spectrum management, EMC at mains frequencies, mobile communications devices and magnetic resonant imaging. There is a concluding chapter on future applications of EM fields in medicine, and useful appendices including a list of suppliers of measurement equipment and a glossary of terms used in electromagnetics. This report will be a valuable reference, particularly for those who design, purchase, install or operate electro-medical devices and equipment.

Essentials of MRI Safety is a comprehensive guide that enables practitioners to recognise and assess safety risks and follow appropriate and effective safety procedures in clinical practice. The text covers all the vital aspects of clinical MRI safety, including the bio-effects of MRI, magnet safety, occupational exposure, scanning passive and active implants, MRI suite design, institutional governance, and more. Complex equations and models are stripped back to present the foundations of theory and physics necessary to understand each topic, from the basic laws of magnetism to fringe field spatial gradient maps of common MRI scanners. Written by an internationally recognised MRI author, educator, and MRI safety expert, this important textbook: Reflects the most current research, guidelines, and MRI safety information Explains procedures for scanning pregnant women, managing MRI noise exposure, and handling emergency situations Prepares candidates for the American Board of MR Safety exam and other professional certifications Aligns with MRI safety roles such as MR Medical Director (MRMD), MR Safety Officer (MRSO) and MR Safety Expert (MRSE) Contains numerous illustrations, figures, self-assessment tests, key references, and extensive appendices Essentials of MRI Safety is an indispensable text for all radiographers and radiologists, as well as physicists, engineers, and researchers with an interest in MRI.

Widely regarded as the standard text on EMC, Tim Williams’ book provides all the key information needed to meet the requirements of the latest EMC Directive. Most importantly, it shows how to incorporate EMC principles into the product design process, avoiding cost and performance penalties, meeting the needs of specific standards and resulting in a better overall product. As well as covering the very latest legal requirements, the fourth edition has been thoroughly updated in line with the latest best practice in EMC compliance and product design. Coverage has been considerably expanded to include the R&TTE and Automotive EMC Directives, as well the military aerospace standards of DEF STAN 59-41 and DO160E. A new chapter on systems EMC is included, while short case studies demonstrate how EMC product design is put into practice. Tim Williams has worked for a variety of companies as an electronic design engineer over the last 25 years. He has monitored the progress of the EMC Directive and its associated standards since it was first made public. He now runs his own consultancy specialising in EMC design and test advice and training. Includes the compliance procedures of the latest EMC Directive: 2004/108/EC Short case studies demonstrating how EMC product design is put into practice Packed full with many new chapters including: The R&TTE Directive and the Automotive EMC Directive looking at compliance aspects of radio and telecom terminal equipment and automotive electronic products; New chapter on military aerospace standards of DEP STAN 59-41 and DO1 60E; New chapter on systems EMC

The possible health effects of electro-magnetic (EMF) from high-voltage electric power lines have been discussed sine the 1970s. The concern was triggered by epidemilogical studies in the United States and Europe that suggested a slightly increased incidence of leukaemia's and brain tumours occured among those living and working near high-voltage power lines. Although studies can indicate an associate between factor and effect, the studies themselves cannot confirm a cause-effect relationship. Whether EMF is producing these ill effects must be confirmed by experimental studies.
