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 ... -
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 ...
