Fundamentals of NMR and MRI, 1st ed. 2024
From Quantum Principles to Medical Applications

This book bridges the gap between physical foundations and medical applications of the NMR and MRI technologies, making them accessible to both physicists and biomedical scientists. The physical basis of these technologies is discussed in a manner that can be easily understood by scientists from different backgrounds, aiding them in gaining a clearer understanding of the subject.. For instance, the medical applications of NMR and MRI technologies are described in a way that is accessible to physicists. Moreover, geometrical descriptions and specific mathematical tools are used to facilitate the visualizations of many concepts. Furthermore, the book covers modern technologies such as hyperpolarization and several other state-of-the-art techniques, along with their foundations.

Dr. Fatemeh Khashami attained her PhD from The University of Texas at Dallas, Department of Physics in 2021. Her dissertation was on Tracking the Biochemistry of Cancer Cells and Dynamics of Physical Systems Using Nuclear Magnetic Resonance. After completing her PhD she joined UT Southwestern Medical Center as a postdoc fellow researcher, where she works on various aspect of NMR and MRI application in medical sciences. Having a PhD in physics from one hand and working on biomedical science on the other hand, has led her to combine these two worlds and develop a particular vision to the NMR and MRI techniques.

Discussed the applications of NMR and MRI, including cutting-edge techniques such as hyperpolarization

Includes a brief intro to quantum mechanics and gradually moves toward the fundamentals of NMR and MRI
