Denoising results—spectra at a particular voxel, marked as “1” in Fig. 3(f), obtained from (a) noisy data; (b) LORA denoising; (c) wavelet shrinkage; (d) sparse 3-D transform-domain collaborative filtering; (e) Gaussian apodization; and (f) noiseless data. Corresponding errors of (b)–(e) are shown in (g)–(j), respectively. All spectra are shown in the real-valued mode.
