Overview
Basics of NMR and MRI linking the physics principles with the engineering requirements/needs and across magnetic field strengths.
This first part will include 7 lectures, 1 meet the teachers session, and 1 discussion at the end. The session will be built as follows:
1- From spin to classical description
2- Bloch equations & relaxation
3- The many sources of MR contrast: T1, T2, T2*
4- Magnet design & shim: general (magnet types, B0 homogeneity & correction)
5- Meet the teachers
6- Magnet design across field strengths (opportunities & constraints)
7- RF pulses: multi-purpose design (spatially/spectrally selective, adiabadic, etc)
8- RF coil design: basics to more advanced
9- Discussion
Target Audience
Physicists and Engineers.
Educational Objectives
As a result of attending this course, participants should be able to:
• Describe the basics of NMR, Bloch equation and contrast mechanisms;
• Explain differences in magnet design across field strengths; and
• Summarize how to generate different RF pulses, from design to execution.
| 08:00 | | From Spin to Classical Description Yang Gao, Xiaotong Zhang Keywords: Physics & Engineering: Physics This lecture explores the fundamentals of nuclear magnetic resonance (NMR), including magnetization, spin excitation, and signal reception. It introduces the formulation of RF fields (B1+ for transmission and B1- for reception) and examines the transition from quasi-static to wave propagation in MRI. Special attention is given to the differences in electromagnetic behavior between clinical (clip_image002.png">3T) and ultra-high field (>3T) MRI, along with the concepts of near-field and far-field effects. This session provides a comprehensive understanding of MRI physics, essential for researchers and clinicians working with advanced imaging techniques. |
