3.4 Microscopic Magnetic Resonance Imaging (μMRI)

In short, magnetic resonance is the absorption of electromagnetic energy by a subpopulation of atomic nuclei in an external static homogenous magnetic field when irradiated at an isotope specific resonance frequency directly proportional to the local magnetic field strength. When the absorbed energy is released upon return to the thermal equilibrium, an inductive signal can be observed which contains chemical and – under special conditions – spatial information about the molecular composition of the irradiated sample. The concept has repeatedly found comprehensive treatment elsewhere – (see, e.g., 2, 306 for spectroscopy and 29, 45 for imaging ) and will therefore only briefly be sketched here.

Atoms exposed to an external magnetic field B0 experience a Zeeman splitting of their energy levels such that the magnetic quantum number m can take on all integer [values between +I and –I, the extremal values of the spin quantum number I, provided that I ≠ 0.]

1.2. Magnetic Resonance Microscopy (MRM)

In short, magnetic resonance is the absorption of electromagnetic energy by a subpopulation of atomic nuclei in an external static magnetic field when irradiated at an isotope-specific resonance frequency directly proportional to the local magnetic field strength. When the absorbed energy is released upon return to the thermal equilibrium, an inductive signal can be observed which contains chemical and – under special conditions – spatial information about the molecular composition of the irradiated sample. The concept has repeatedly found comprehensive treatment elsewhere – see, e.g., Abragam (1961) or Slichter (1978) for spectroscopy and Callaghan (1991) or Blümich and Kuhn (1992) for imaging – and will therefore only briefly be sketched here.
