摘要: Publisher Summary The scattering analogy provides a useful description of the Pulsed Gradient Spin Echo (PGSE) method. It lends itself naturally to use Fourier analysis and mathematics diffraction when designing PGSE experiments in treating resulting echo signals. Care is needed allowing for finite time, pulse width relaxation effects. This chapter examines conventional least squares approaches multi-parameter fitting that can result valuable structural dynamical insight. When used as contrast imaging, method allows motion be spatially localized. access local propagator permits procedures, which reveal motional features specific interest. sophisticated localized offers promising avenues investigation development more powerful nuclear magnetic resonance (NMR) imaging methodologies.
