Concluding a journey through MRI.The purpose of this book is to provide a conceptual approach to understanding the basics of MRI. This book develops materials along a clinical perspective along with a technological examination of how MRI works. Radiology residents, technologists, and technical sales specialists who want to understand the goals of clinical scanners will find this book useful. This book further supports application-oriented MRI objectives of MP3.0 for MRI scientists., medical physicists, and biomedical engineers. MRI concepts and practices have developed enormously over the last 30 years, and this book provides readers with a start to up-to-date overview of current techniques and practices. Part of IPEM-IOP Series in Physics and Engineering in Medicine and Biology.Medical residents, researchers, radiology technologists.Also available in print.Mode of access: World Wide Web.System requirements: Adobe Acrobat Reader, EPUB reader, or Kindle reader.Dr. Dee Wu is a Professor and Chief of Technology Applications and Translational Research in the department of Radiological Sciences at OU Health. He also serves as an affiliate of the School of Computer Science and Electrical Engineering at the University of Oklahoma and has worked as an MRI Scientist and a Medical Physicist for over 30 years. Dr Wu has passion for education and engages in collaborative exchanges with many different professions and medical subspecialties in his practice.Title from PDF title page (viewed on March 3, 2023).
