DOSIMETRIC STUDY OF BETA-MINUS EMITTER PRASEODYMIUM-142 : APPLICATIONS IN MICROSPHERE BRACHYTHERAPY FOR HEPATOCELLULAR CARCINOMA AND BRACHYTHERAPY FOR OCULAR SQUAMOUS CELL CARCINOMA
(East Carolina University, 2013)A dosimetric study of the beta-minus emitter Praseodymium-142 (¹⁴²Pr) was performed and two main innovative applications of this source in brachytherapy are proposed: microsphere brachytherapy and eye plaque brachytherapy. ... -
Elastic and inelastic light scattering from single bacterial spores in an optical trap allows the monitoring of spore germination dynamics
(East Carolina University, 2009-05-15)Raman scattering spectroscopy and elastic light scattering intensity (ESLI) were used to simultaneously measure levels of Ca-dipicolinic acid (CaDPA) and changes in spore morphology and refractive index during germination ... -
Electron Emission from Fast Proton and Carbon Ion Interactions with Gold Nanoparticles and Amorphous Solid Water
(East Carolina University, 2021-07-22)Widely used in the treatment of cancer, radiation therapy delivers a lethal dose of energy to malignant tissue. Modeling the deposition of energy in the interactions of the radiation with biological material is important ... -
Electron Emission from Foils and Biological Materials after Proton Impact
(East Carolina University, 2008-10)Electron emission spectra from thin metal foils with thin layers of water frozen on them (amorphous solid water) after fast proton impact have been measured and have been simulated in liquid water using the event-by-event ... -
EVALUATING THE USE OF TURBIDIMETRY FOR STUDYING FIBRIN STRUCTURAL PROPERTIES
(East Carolina University, 2023-04-21)A fibrin fiber mesh forms the structural backbone of blood clots. Many pathological conditions result in fibrin gels with altered structural properties, so there is interest in developing rapid and accurate ways to ... -
Evaluation of Magnetic Resonance Imaging in Prostate Radiotherapy for Improved Treatment Outcomes
(East Carolina University, 2019-05-01)External beam radiation therapy is among the most common modalities of curative treatment for prostate cancer and has evolved substantially with the inclusion of multimodality imaging in treatment planning. It has been ... -
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 ...
