Brian M. Dale, Ph.D. MBA is Zone Research Manager, MR R&D Collaborations, Siemens Medical Solutions, Inc. Brian is a younger colleague at Siemens of the previous co-author, Dr Mark Brown. Brian has a PhD in biomedical engineering from Case Western Reserve University in Cleveland, OH. His interests are in sequence programming and optimal design.Mark A. Brown, Ph.D. is Senior Technical Instructor at Siemens Medical Solutions Training and Development Center. He received his Ph.D. in Physical Chemistry from Duke University, in Durham, NC. His research interests include relaxation and exchange phenomena and in vivo nuclear magnetic resonance spectroscopy and imaging.Richard Semelka, MD, is Director of Magnetic Resonance Services, Professor, and Vice Chairman of Radiology at the University of North Carolina-Chapel Hill Medical School. He received his medical degree and residency training in radiology in his native Canada at the University of Manitoba, and completed a clinical research fellowship in MRI of the body at the University of California at San Francisco. Dr. Semelka has authored over 300 peer-reviewed articles, 12 textbooks including the Wiley Abdominal-Pelvic MRI and Current Clinical Imaging series and is an internationally acclaimed authority in the field.
