Novel methods for quantifying lung and cardiac diseases with magnetic resonance imaging
(University of Missouri--Columbia, 2023)
[EMBARGOED UNTIL 5/1/2024] Magnetic Resonance Imaging (MRI) is an advanced imaging technique that has transformed the field of medical diagnosis and treatment. In the field of lung and cardiac imaging, MRI boasts the ...
Development of high-resolution optical tomography with a larger-size projection acquisition
(University of Missouri--Columbia, 2007)
In the industrial countries, the mortality from arteriosclerosis and cardiovascular diseases has been decreased, but they remain the most common circulatory disease. Recently, new tissue engineering technologies such as ...
Time delay compensation in finite-order models of acoustic wave propagation in homogenous media
(University of Missouri--Columbia, 2011)
Finite-order models do not completely account for the delay in acoustic wave propagation and thus require an additional phase correction, besides parameter adjustments to fit experimental measurements. As a consequence, ...
A simplified holistic model of pulmonary oxygen transfer and its application in assessing exercise ability of pulmonary patients
(University of Missouri--Columbia, 2023)
rate, and CPT (p[less than]0.05) compared to resting normoxia. Do increased during SSH+CPT compared to SSH alone (p[less than]0.05). The OD method was applicable to only 9 participants and did not show any difference among treatment conditions (p...
A fiber-optic confocal scanner for scattering tissue
(University of Missouri--Columbia, 2009)
Confocal microscopy has become an important diagnostic tool in examining scattering tissues. The high resolution of confocal microscopy and its optical sectioning capabilities lend itself as a desirable modality in examining ...
Imaging structurual and mechanical properties in cardiovascular tissue using optical polarization tractography
(University of Missouri--Columbia, 2022)
resolution, however, they are limited by their small field of view and their insufficient effective imaging depth. To address these issues, this dissertation focuses on characterization of the fiber architecture of Extra Cellular Matrix (ECM...
The role of sodium-calcium exchanger in the electrical activity of embryonic chicken heart
(University of Missouri--Columbia, 2008)
Heart is one of the most important organs of the body and also it is one of the first organs during to the development. The electrical activity of heart is essential for its function. It has been shown that the sodium-calcium ...
Design and characterization of a hand-held, waveguide-mediated, optoacoustic imaging probe for analyzing burn wounds
(University of Missouri--Columbia, 2018)
Clinicians correctly diagnose only [about]66% of burn wounds, which may be in part due to the qualitative methods commonly employed for burn assessment. This often results in over diagnoses, which may lead to unnecessary ...
Development of a flexible image-based approach for studying signal transduction in isolated arterioles
(University of Missouri--Columbia, 2007)
Myogenic constriction in arterioles occurs when membrane tension leads to smooth muscle depolarization and voltage-gated calcium channel activation. A barrier to understanding the exact signaling events is the limited ...
Modeling the influence of climate and management practices on water quality in Goodwater Creek experimental watershed
(University of Missouri--Columbia, 2006)
The objective of this study was to determine relationships among weather, runoff, water quality, and best management practice (BMP) implementation in reducing atrazine losses in the 7,250-ha Goodwater Creek Experimental ...
Photoacoustic detection of metastatic melanoma in the human circulatory system
(University of Missouri--Columbia, 2006)
Detection of disseminating tumor cells can function as an early warning system, alerting the metastatic spread or recurrence of the disease. Early detection of such cells can result in preventative treatment of the disease ...
