Ultra-sensitive tunable laser absorption spectroscopy: Applications and performance assessment
Methodologies using tunable laser absorption spectroscopy (TLAS) for quantifying carbon dioxide stable isotopes (13/12CO 2), measuring atmospheric formaldehyde (CH2O), and analyzing exhaled carbonyl sulfide (COS) in human ...
Respiratory motion correction techniques in positron emission tomography/computed tomography (PET/CT) imaging
The aim of this thesis is to design, implement, and evaluate respiratory motion correction techniques that can overcome respiratory motion artifacts in PET/CT imaging. The thesis is composed of three main sections. The ...
Segmenting contrast-enhanced CT images for attenuation correction of PET/CT data
The use of contrast media in positron emission tomography (PET)/computed tomography (CT) dual modality imaging has been shown to cause artifacts in the PET image. These artifacts are attributed to an overestimation of the ...
Motion-corrected treadmill nuclear angiography
First-pass radionuclide angiography (RNA) of the human heart is performed during peak treadmill exercise using a Multiwire Gamma Camera (MWGC) and an intravenous injection of ultra-short-lived radionuclide Tantalum-178. ...
Characterizing the afferent limb of the baroreflex
In this study, we develop a model of left ventricular and near-systemic hemodynamics, together with a three-component model of the aortic baroreceptor (BR) using experimental data from rat. The hemodynamic model possesses ...
