Incorporation of phase changes in functional magnetic resonance imaging
Functional magnetic resonance imaging (fMRI) data is acquired as a complex image pair including magnitude and phase information. The vast majority of fMRI experiments do not attempt to take advantage of the time varying phase information. The phase of the MRI signal is related to the local magnetic …

On the Use of Independent Component Analysis & Functional Network Connectivity Analysis: Evaluation on Two Distinct Large-Scale Psychopathology Studies
… suffering from mental disorders. Functional magnetic resonance imaging (fMRI) is one of the leading techniques currently being implemented to explore cognitive function and aberrant brain activity resulting from mental illness. Functional connectivity has investigated the associations of …

Optimal spectral reconstructions from deterministic and stochastic sampling geometries using compressive sensing and spectral statistical models
… the aliasing effects of under-sampled Fourier data. The proposed solution utilizes an additional layer of optimization to enhance the performance of a previously published CS reconstruction algorithm. Specifically, the new framework provides reconstructions of a desired image quality by jointly …
