Under-Sampled Reconstruction Techniques For Accelerated Magnetic Resonance Imaging, Mohammad H. Kayvanrad
Electronic Thesis and Dissertation Repository
Due to physical and biological constraints and requirements on the minimum resolution and SNR, the acquisition time is relatively long in magnetic resonance imaging (MRI). Consequently, a limited number of pulse sequences can be run in a clinical MRI session because of constraints on the total acquisition time due to patient comfort and cost considerations. Therefore, it is strongly desired to reduce the acquisition time without compromising the reconstruction quality. This thesis concerns under-sampled reconstruction techniques for acceleration of MRI acquisitions, i.e., parallel imaging and compressed sensing.
While compressed sensing MRI reconstructions are commonly regularized by penalizing the decimated wavelet …

Effect Of Fluid Loss Following Hemodialysis On Tibialis Anterior Muscle Strength In People With End-Stage Renal Disease, Anuradha Sawant
Electronic Thesis and Dissertation Repository
ABSTRACT
PURPOSE: The purpose of this study was to evaluate the effect of fluid loss following hemodialysis (HD) on tibialis anterior (TA) strength in participants with end-stage renal disease. Issues concerning measures of skeletal muscle hydration and efficacy of exercise as an anabolic intervention were also addressed.
METHODS: Data from published literature were combined in a meta-analysis to establish efficacy of exercise in participants on HD. Three clinical studies were undertaken using data acquired from healthy volunteers and participants on HD. Hydration of the calf muscles was estimated using bioelectrical impedance spectroscopy (BIS) [extracellular (ECF) and intracellular (ICF) fluid] …
