Abstract

In one aspect, a nuclear magnetic resonance (NMR) system includes a transmitter to output a main refocusing pulse sequence and at least one subsequent refocusing pulse sequence into a zone of interest, a randomizing pulse module to output a randomizing pulse into the zone of interest to remove a net detected residual magnetization, and a receiver to output an NMR data set from the zone of interest. In another aspect, a method of generating a nuclear magnetic resonance (NMR) data set includes outputting a main refocusing pulse sequence and at least one subsequent refocusing pulse sequence into a zone of interest, outputting a randomizing pulse from a randomizing pulse module into the zone of interest to remove a net detected residual magnetization, and sensing the NMR data set from the zone of interest.
