Abstract:
A method for operating a magnetic resonance apparatus, comprising the steps of:recording a magnetic resonance signal for a time span comprised of a plurality of time segments and thereby receiving a recorded magnetic resonance signal having a signal segment respectively in each of said time segments; after receiving said recorded magnetic resonance signal, weighting said recorded magnetic resonance signal with a bell-shaped window function to obtain a weighted magnetic resonance signal; Fourier transforming said weighted magnetic resonance signal only after said weighting, to produce a magnetic resonance spectrum; weighting at least one of said magnetic resonance signal segments respectively recorded in at least one of said time segments with an additional bell-shaped window function having a window width that is approximately equal to, and disposed within, said at least one of said time segments, to obtain an additionally-weighted segment of said magnetic resonance signal; and subjecting said additionally-weighted segment of magnetic resonance signal to an additional Fourier transformation, to make at least one non-dominant resonant line in said magnetic resonance signal more precise.
