Methods, systems, software arrangements and storage medium for measuring the magnetic field correlation function ('MFC'), and more particularly, to methods for measuring the magnetic field correlation function utilizing asymmetric spin echoes. Asymmetric Dual Spin Echo Sequences ('ADSE') and Echo Planar Imaging Asymmetric Dual Spin Echo Sequences (&#x201c;EPI-ADSE&#x201d;) may be employed to apply multiple echoes to a sample and acquire data from which the MFC may be determined.

Method, system and software arrangement, for measuring magnetic field correlation

For use in nuclear magnetic resonance (NMR) spectroscopy and magnetic resonance imaging (MRI), a method and apparatus for signal acquisition are disclosed. Preferred processing involves elimination of an unwanted signal by subtraction, in the time domain, of a cancellation signal from a free-induction-decay actual signal. A cancellation signal may be obtained, e.g., by smoothing a free-induction-decay signal, by curve fitting, or by computer simulation.
