Magnetic Resonance Imaging: Principles and Applications

This lecture introduces the principles of magnetic resonance imaging (MRI) and its applications in chemistry, materials science, and medicine. Starting with the Zeeman effect and NMR spectroscopy, it covers topics such as multi-dimensional NMR, Fourier imaging, and image contrast mechanisms. The instructor discusses the role of magnetic field gradients, inverse space acquisition, and the Fourier transform in NMR signal processing. The lecture explores the detection period in NMR experiments, k-space trajectory in imaging, and technical limitations in spatial resolution. It also delves into the significance of multi-dimensional spectroscopy and the acquisition of 2D and 3D images using MRI scanners.
