A study on the application of independent component analysis to \(in vivo\) \(^1\)H magnetic resonance spectra of childhood brain tumours for data processing
Independent component analysis (ICA) has the potential of automatically determining metabolite, macromolecular and lipid (MMLip) components that make up magnetic resonance (MR) spectra. However, the realiability with which this is accomplished and the optimal ICA approach for investigating in vivo …
