Fundamental Principles of MRI

  • Michael J. McCarthy


Accurate descriptions of the state of microscopic particles such as electrons, atoms, or nuclei generally require the use of quantum mechanics. For NMR experiments, the interaction of the nuclear magnetic moments with an applied internal field is used to examine the chemical environment within the sample. Magnetic moments arise from orbital angular momentum and spin angular momentum of a changed particle.
