A Subspace Approach to Spectral Quantification for MR Spectroscopic Imaging
A new subspace approach to spectral quantification for MR spectroscopic imaging (MRSI) is reported. It represents the spectral distribution of each molecule using a low-dimensional subspace and the entire spectrum as a union-of-subspaces.
Improved Low-Rank Filtering of Magnetic Resonance Spectroscopic Imaging Data Corrupted by Noise and B0 Field Inhomogeneity
This paper presents an improved low-rank method for denoising magnetic resonance spectroscopic imaging data. The method will enhance the practical utility of high-resolution magnetic resonance spectroscopic imaging, where low signal-to-noise ratio has been a limiting factor.
