Abstract: Nuclear or electron spin magnetic resonance method using multiple radial scans through frequency-space. The problem of insufficient sample density at the higher image frequencies is solved by deriving an edge image, determining a correction image therefrom by using a priori knowledge about the pixel value distribution and using the correction image after Fourier transformation to frequency-space.

Abstract: A method of and device for the determination with high computational efficiency of spectrum parameters of a spectrum utilizes quantification and model fitting of sampling values of a signal in the time domain on the basis of a model function comprising exponentially damped sinusoids. The method starts with a coarse estimation of a number of spectrum parameters, followed by linearization of the model function and iterative estimation of the coarsely estimated parameters and further parameters, utilizing a least-squares optimization procedure where inner product terms are brought into analytic form and are preferably recursively determined.
