We propose real-time voxel shift for grid-free computer resource-efficient analysis of CSI data as an alternative to spatial Fourier-interpolation prior to analysis. Spectral information is extracted from CSI data at every mouse click at any location of the object to study with accurate display of the voxel shape and size. Voxel-shift applied sequentially has also permitted extraction of spectra from arbitrarily shaped compartments as well as calculation of B0-corrected metabolite maps using AMARES time-domain fitting.
