Regularized Spectral Lineshape Deconvolution
Introduction Quantitative analysis of in vivo Magnetic Resonance Spectroscopy (MRS) is often hampered by lineshape distortions resulting from the magnetic field B0 inhomogeneities and eddy currents. The knowledge of lineshape is therefore needed for spectral quantifications, especially in the presence of overlapping resonance lines. Although a model function can be used to fit a non-analytical ...
متن کاملRegularized Blind Deconvolution
Image restoration involves the removal or minimization of degradation (blur, clutter, noise, etc.) in an image using a priori knowledge about the degradation phenomena. Blind restoration is the process of estimating both the true image and the blur from the degraded image characteristics, using only partial information about degradation sources and the imaging system. Our main interest concerns...
متن کاملComputational modeling of spectral data fitting with nonlinear distortions
Substances such as chemical compounds and biological agents are invisible to human eyes, they are usually captured by sensing equipments with their spectral fingerprints. Although spectra of pure substances can be identified by visual inspection, the spectra of their mixtures take a variety of complicated forms. Given the knowledge of spectral references of the constituent substances, the task ...
متن کاملQuantitative measurement of N-acetyl-aspartyl-glutamate at 3 T using TE-averaged PRESS spectroscopy and regularized lineshape deconvolution.
This article introduces regularized lineshape deconvolution in conjunction with TE-averaged PRESS spectroscopy to measure N-acetyl-aspartyl-glutamate (NAAG). Averaging different echo times suppressed the signals of multiplets from strongly coupled spin systems near 2 ppm; thus, minimizing the interfering signals to detect the acetyl proton signal of NAAG. Signal distortion was corrected by line...
متن کاملSpectral lineshape reflects microscopic structure and ordering
Introduction: The cellular structure of living tissues is much finer than the achievable resolution of MRI images. Water molecules diffusing through the tissue explore its microstructure, but the observed signal, the sum of all spin contributions, is effectively averaged over macroscopic voxels, so that most of the subvoxel information is lost. The relevant question is which of the structural p...
