A Study of Ensemble Machine Learning Model Architectures for Parkinson’s Disease Detection and Freezing of Gait Forecasting
DownloadFall 2021
Parkinson's Disease (PD) is a major progressive neurological disorder and is extremely difficult to diagnose PD~\cite{pmid23039866} since there are no defined medical tests for this task. The existing approach involves a combination physical examinations, neuroimaging and demographic analysis...

Background: Intracerebral Hemorrhage (ICH) is associated with high morbidity and patients commonly suffer motor dysfunction. ICH volume is a significant predictor of outcome, and perihematoma edema may also represent tissue injury. Diffusion Tensor Imaging (DTI) can be used to assess in-vivo...

Magnetic resonance imaging (MRI) is a valuable imaging modality and is commonplace in diagnosing, evaluating, and understanding the pathobiology of many neurological disorders. Current methods are helpful in the diagnosis of multiple sclerosis (MS) but fail to provide useful longitudinal...

Spinal cord injury is most commonly caused by physical trauma, and the resulting functional loss can vary considerably in both degree, extent and location. Understanding what spinal cord tissue is damaged and to what degree can be useful in both determining the appropriate treatment for...

Geochronology and Trace Element Characteristics of Pyrite from Selected Carbonate Hosted Pb-Zn Ore Deposits
DownloadFall 2012
Carbonate-hosted ore deposits, such as Mississippi Valley-type (MVT), and Irish-type deposits, are a major class of Pb-Zn ores. Due to the mineralogy of these deposits, numerical constraints on the timing of mineralization are few. This thesis investigates pyrite Re-Os geochronology for dating...

Hippocampal Diffusion Tensor Imaging in Parkinson's Disease and Associations with Non- Motor Symptoms
DownloadSpring 2023
Parkinson’s disease (PD) is the second most common neurodegenerative disorder and causes not only well-characterised motor symptoms, but also a host of non-motor symptoms that greatly impact quality of life. PD exists within a larger spectrum of disorders caused by the accumulation of Lewy bodies...

A promising approach to the development of an integrated system for magnetic resonance imaging-guided radiotherapy involves the rigid coupling of a medical linear accelerator to a rotating biplanar magnet assembly. Through near real-time volumetric imaging during irradiation, this hybrid system...

Measurement and Correction for the Magnetic Susceptibility Effects of Fat in Venous Oximetry: Application in the Quantification of Muscle Oxygen Consumption (VO2) with Plantar Flexion Exercise
DownloadSpring 2018
Measuring venous oxygen saturation (SvO2) provides direct assessment of the upstream muscle or organ's ability to extract and metabolize oxygen. Previously, measurement of venous oxygen saturation has been performed in most studies by intravenous catheterization. This approach has the advantage...

MRI-Based Texture Analysis for Characterizing Cerebral Degeneration Progression in Amyotrophic Lateral Sclerosis
DownloadFall 2024
Amyotrophic lateral sclerosis (ALS) is a highly heterogeneous, progressive neurodegenerative disease with a median survival of three years from the onset of symptoms. As a multi-system disease, ALS is not limited to the motor system and includes degeneration of other cerebral regions, including...

Magnetic resonance imaging (MRI) is a universally-used tool in clinical neurosurgery. It has revolutionized preoperative diagnosis, surgical planning, intraoperative targeting, and postoperative surveillance. Nevertheless, the idea that early, quantifiable perioperative structural changes of the...
