Quantitative Susceptibility Mapping in Human Brain: Short Echo Timing, Thin Slab, and Non-harmonized Multisite Applications
DownloadSpring 2023
Quantifying tissue magnetic susceptibility provides a non-invasive way to monitor iron and myelin abnormalities associated with several neurodegenerative diseases. Quantitative susceptibility mapping (QSM) is a post-processing technique that retrieves the susceptibility distribution from the...

Quantitative Susceptibility Mapping in Ischemic Stroke: Cerebral Veins, Tissue, and Microbleeds
DownloadSpring 2019
Quantitative susceptibility mapping (QSM) is an emerging magnetic resonance imaging (MRI) post-processing technique that uses phase images from a gradient echo sequence to create magnetic susceptibility maps. QSM is sensitive to paramagnetic iron found in various states of blood, from...

Spring 2016
Quantitative transverse relaxometry is an MRI method that has shown promise for study of iron accumulation and demyelination in healthy brain and in associated neurological disorders. Multiple sclerosis (MS) is one such neurodegenerative disorder in which iron accumulation in deep grey matter...

Spring 2017
In magnetic resonance imaging (MRI), radio frequency (RF) detectors or “coils” are used to excite and receive signal from the nuclear spins. This thesis focuses on the design and development of RF coils and methods to achieve the best possible image quality at high static magnetic field strengths...

Spring 2013
Spastic hypertonus is a sensorimotor disorder characterized by involuntary muscle over-activity. Hypertonus emerges in the days and months following upper motor neuron lesions such as spinal cord injury, stroke or multiple sclerosis and affects millions of individuals around the world. Hypertonus...

Reliability of Three-dimensional Ultrasound Parameters and Their Correlation with the Progression of Adolescent Idiopathic Scoliosis
DownloadFall 2016
Adolescent idiopathic scoliosis (AIS) is a three-dimensional (3D) spinal deformity with unknown causes and with prevalence of 1.5 - 3% of adolescents. If AIS is left untreated, it may progress, leading to back pain, cardiopulmonary problems, and psychosocial concerns, and eventually resulting in...

Spring 2013
The overall goal of this thesis was to develop a proof-of-principle for a device that might eventually restore walking in people with paraplegia. The thesis consisted of three component technologies each working in conjunction with one another in adult cats. The first component was the...

Revealing Key Movement Strategies in Upper Limb Function Using a Novel Standardized Kinematic Assessment Tool
DownloadSpring 2020
Introduction: Artificial limbs, also known as prostheses, are used by individuals with upper limb loss to replace some of the functionality of the upper limb. Given the wide range of tasks and movements the upper limbs can accomplish, replacing full functionality can be challenging. While...

Simultaneous Measurement of Blood Flow and Oxygen Consumption Immediately Post-Exercise with Magnetic Resonance Imaging
DownloadFall 2014
Invasively measuring blood flow and oxygen consumption during exercise has been used to help advance performance, stratify fitness levels and most importantly to aid in clinical diagnoses and track disease or recovery progression. There is currently no non-invasive method for measuring skeletal...
