Quantitative analysis of magnetic resonance time domain signals

A magnetic resonance time domain signal is often made up of a limited number of exponentially decaying sinusoids plus white noise. Traditionally, quantitative analysis of the signal is carried out in the frequency domain, after applying FFT in conjunction with a time window. It is shown that quantitative analysis directly in the time domain is feasible, and in fact yields several advantages. Various methods are applied and compared. (Auth.)
