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.
