Physics for understanding fMRI artifacts: CONTENTS

Figured it might be useful to have some summary/contents pages. I'll do similar admin posts as the other series mature, too. And I will label these pages with "Contents" to make them easier to find via the sidebar.


Part One

An introduction to the series, followed by an introductory video courtesy of Sir Paul Callaghan: What is NMR and how does it work?


Part Two

Further videos explaining the principles of nuclear magnetic resonance - how the intrinsic spin of certain atomic nuclei interacts with applied magnetic fields to yield useful information.


Part Three

Videos showing the anatomy of a miniature scanner, a basic NMR experiment, why shimming is important for NMR (and MRI), how and why a spin echo works, and the relaxation of spins back towards their ground state.


Part Four

Mathematics of oscillations: an introduction to imaginary and complex numbers, and frequency and phase.
