The normalization takes into account that small signal differences can easily be masked when the overall signal intensity is high. It should be kept in mind that the ability to…
([1]) where N m is the number of spins in the state m, N 0 is the total number of spins, E m is the energy of the state m,…
([1]) where γ is the gyromagnetic ratio; ћ is Planck’s constant divided by 2π; P is the nuclear spin polarization. Therefore, it is clear that a higher spin concentration and…
([1]) where B 0 is the strength of the external magnetic field (measured in Tesla), ω 0 and ν 0 are the angular velocity and frequency of the precession, respectively,…
, does not contain any position-dependent terms. It is thus necessary to introduce some spatially varying factor that allows distinguishing between spins at different positions in space. This is achieved…
