Parameter estimation for in vivo magnetic resonance spectroscopy (MRS) using simulated annealing.
A method for estimating the spectral parameters from a noisy FID is proposed. The method uses a priori information concerning the lower and upper limits between which such parameters' values can exist. Computer simulation results show that, using the proposed method, values of the spectral parameters can be accurately estimated from a noisy FID.
