Pages: 307 Publisher: People's Medical Publishing magnetic resonance imaging in the field of medical imaging other imaging methods. the higher the requirements of the operator: Only under the premise of understanding of the basic physical principles. the imaging results to the most accurate explanation. For practitioners of magnetic resonance imaging technology. not only to know these. but also to know why. For this purpose. the in-depth understanding of the MRI base pragmatic at the same time. more emphasis on the interpretation of the basic theory. In-depth understanding of the MRI base step-by-step introduction to the basics of all aspects of magnetic resonance imaging. Each chapter is designed to answer specific questions. From the concept of the nuclear magnetic resonance to a variety of imaging applications. the reader can have a complete understanding of the technology. In-depth understanding of MRI based focus on the introduction of basic theory. but not entirely Aspect complex mathematics and electronics knowledge. The audience is mainly medical students. doctors of the Department of Radiology and magnetic resonance imaging researchers. Contents: Chapter 1 NMR review: Chapter 2 of the interpretation of the magnetic field and current. electromagnetic relationship Nuclear magnetic resonance phenomenon. the classical model. the relaxation phenomena of quantum model of Chapter 3. the longitudinal and transverse magnetic concept . the longitudinal relaxation T1.
