Abstract
Magnetic field temporal variations in magnetic resonance imaging (MRI) volume are determined based on the slope of a phase difference Δφ between spin responses in plural slices at a given temporal sampling time. Representations of the determined temporal magnetic field variations are stored for subsequent use, e.g., to achieve more accurate re-gridding of acquired k-space date before reconstruction of images in the spatial domain.
