This work proposes an overdiscrete reconstruction for Single Voxel Spectroscopy (SVS). It is demonstrated that in single voxel acquisitions benefit from the SNR and linewidth improvement obtained by correcting for of B0 inhomogeneities and the optimization of the Spatial Response Function (SRF), as compared to regular signal averaging. This method, enables SV acquisitions in challenging brain areas, i.e. where B0 shimming is sub-optimal, and corrects for spectral artifacts such as peak aliasing.
