Fast Carbon-Ion and Proton Induced Electron Emission from Condensed-Phase Biological Targets
(East Carolina University, 2018-07-23)Fast charged particles interact with matter through various ionization and excitation pathways that aren't fully understood. Predicting the effects of these interactions is vital in many fields such as radiation therapy, ... -
Feasibility Study of Dual Energy Radiographic Imaging for Target Localization in Radiotherapy for Lung Tumors
(2014)Purpose Dual-energy (DE) radiographic imaging improves tissue discrimination by separating soft from hard tissues in the acquired images. This study was to establish a mathematic model of DE imaging based on intrinsic ... -
FETUS PHANTOM CONSTRUCTIONS FOR OVERWEIGHT AND OBESE PREGNANT FEMALES FOR RADIOLOGICAL APPLICATIONS
(East Carolina University, 2019-06-07)Radiation exposure and associated radiation risks are major concerns for fetal development for pregnant patients in general, and in particular for overweight and obese pregnant patients who undergo diagnostic imaging or ... -
Fiducial Marker Placement and Selection Study for Real-Time Lung Tumor Tracking
(East Carolina University, 2023-04-26)Introduction: Lung cancer remains one of the most fatal forms of cancer globally. Lung cancer is often treated by surgical removal of the malignant tissue however, surgery is not often an option for lung cancer. Radiation ... -
Flow cytometer apparatus for three dimensional diffraction imaging and related methods
(2009-12-17)A flow cytometer assembly includes a fluid controller configured to form a hydrodynamically focused flow stream including an outer sheath fluid and an inner core fluid. A coherent light source is configured to illuminate ... -
Flow cytometer apparatus for three dimensional difraction imaging and related methods
(2015-04-21)A flow cytometer assembly includes a fluid controller configured to form a hydrodynamically focused flow stream including an outer sheath fluid and an inner core fluid. A coherent light source is configured to illuminate ... -
Four-Dimensional In Vivo Dosimetry By Dose Reconstruction Using Continuous Epid Images And Phase Sorting Method
(East Carolina University, 2015)In vivo dosimetry is widely used for patient specific dose evaluation and treatment verification in external beam radiation therapy (EBRT). There is a growing interest in using an electronic portal imaging device (EPID) ... -
Generation of Pseudo-CT using Two Sets of MRI Scans for MRI-only Radiation Therapy
(East Carolina University, 2019-07-16)WWith increasing interests in magnetic resonance imaging (MRI)-only radiation therapy (RT) and the emergence of MRI system integrated with the linear accelerator, a method substituting the computed tomography (CT) in ... -
Graviton and photon orbitals surrounding a black hole : Application to the supermassive black hole at the Milky Way galactic center, with NIR observational confirmation.
(East Carolina University, 2014)Non-relativistic Quantum Theory fairly accurately describes the resonance phenomena around a black hole, even though black holes are thought of as general relativistic (GR) objects. Graphically and numerically we are able ... -
The high concentration of Arg213 → Gly extracellular superoxide dismutase (EC-SOD) in plasma is caused by a reduction of both heparin and collagen affinities
(East Carolina University, 2005-01-15)The C-terminal region of EC-SOD (extracellular superoxide dismutase) mediates the binding to both heparin/heparan sulphate and type I collagen. A mutation (Arg213→Gly; R213G) within this extracellular matrix-binding region ... -
How Moist Heat Kills Spores of Bacillus subtilis
(East Carolina University, 2007-12)Populations of Bacillus subtilis spores in which 90 to 99.9% of the spores had been killed by moist heat gave only two fractions on equilibrium density gradient centrifugation: a fraction comprised of less dense spores ... -
Improved Quark Coalescence for a Multi-Phase Transport Model
