Signal-to-noise enhancement in magnetic resonance spectroscopic imaging |
摘要 |
<p>A magnetic resonance imaging system capable of conducting spectroscopic imaging with an improved SNR without degrading the spatial resolution includes edge-preserving filter processing means (502) for spectroscopic imaging. The edge-preserving filter processing means executes processing including the steps of calculating (514) spectral similarity in spatial neighborhoods (spatially neighboring voxels) at each voxel in spectroscopic imaging data, calculating (515, 517) a spectral weight according to the spectral similarity, and conducting (519) weighted smoothing for compounding spectra of spatial neighborhoods (spatially neighboring voxels) according to the spectral weight.</p> |
