Beschreibung:
Basic Introduction to Bioelectromagnetics, Third Edition, is a primary source for medical technologists and life scientists seeking to understand how electromagnetic fields interact with the body, and how they are used in medical applications. Instead of the complex math commonly used when analyzing electromagnetics, this book uses graphical methods and simple equations. The third edition is updated with color graphics that show the fields in bright, clear colors. Each concept is presented with an associated discussion and application, including MRI, NMR, hyperthermia, neural stimulation, ultrasound, and cardiac pacing/defibrillation.
