Principles of Nuclear Magnetic Resonance Microscopy Paul Callaghan
Publisher: Oxford University Press, USA

The basic However, existing techniques either have poor spatial resolution compared to optical microscopy and are hence not generally applicable to imaging of sub-cellular structure (for example, magnetic resonance imaging), or entail operating conditions that preclude . Nuclear magnetic resonances in the presence of magnetic field gradients have been studied extensively in connection with magnetic resonance imaging 1 .

The high information content of modern multi-dimensional Although the hyperpolarization strategies differ in their underlying physico-chemical principles they have a number of problems in common. NMR phenomena instead of nuclei. The basic principles are otherwise similar. Magnetic resonance microscopy: recent advances and applications. Nuclear Magnetic Resonance (NMR) spectroscopy, microscopy and imaging techniques (MRI) play a crucial role in numerous fields of science ranging from physics, chemistry, material sciences, biology to medicine. The resulting response to the perturbing magnetic field is the phenomenon that is exploited in NMR spectroscopy and magnetic resonance imaging, which use very powerful applied magnetic fields in order to achieve high resolution spectra, details of which are described by the chemical shift and the Zeeman effect. Researchers increase NMR/MRI sensitivity through hyperpolarization of nuclei in diamond. Optical-atomic magnetometers are based on a different principle – one that, curiously, is something like NMR in reverse, except that optical-atomic magnetometers measure whole atoms, not just nuclei. The general principles of the magnetic imaging technique used here have been known for some time.
