Abstract
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.
