Enhancement of NMR vertical resolution using walsh function based inversion
摘要:
NMR data are acquired using a phase-alternation of the tipping pulse. Averaged properties are estimated over a window length. The averaged properties are inverted to undo the effects of the averaging. A matrix defined in terms of Walsh functions is used in the inversion.
