A Deep-Learning Method of Automatic VMAT Planning via MLC Dynamic Sequence Prediction (AVP-DSP) Using 3D Dose Prediction: A Feasibility Study of Prostate Radiotherapy Application
(2020)Introduction: VMAT treatment planning requires time-consuming DVH-based inverse optimization process, which impedes its application in time-sensitive situations. This work aims to develop a deep-learning based algorithm, ... -
Accelerating Brain DTI and GYN MRI Studies Using Neural Network
(2021)There always exists a demand to accelerate the time-consuming MRI acquisition process. Many methods have been proposed to achieve this goal, including deep learning method which appears to be a robust tool compared ... -
Commissioning a State-of-Art Small Animal Irradiator and Novel Mini-GRID Treatment Technique
(2022)Purpose: To validate commissioning results associated with the Xstrahl Small Animal Radiation Research Platform (SARRP) installed at Duke University in October 2021, verify the accuracy of the Xstrahl Point Dose Calculator ... -
Design and Qualification of a Coded Aperture Cycloidal Mass Spectrometer to Detect Perfluorocarbon Tracer Molecules for Environmental Applications
(2022)In urban, dense, and/or environmentally sensitive regions, underground high-pressure fluid-filled (HPFF) transmission cables are used to transport electricity at high voltages to prevent electrical losses. With age and use, ... -
Dosimetric and radiobiological fitting of xerostomia and dysphagia 12 months after treatment for head and neck tumors
(2018)Oropharyngeal Squamous Cell Carcinoma (OPSCC) is by far the most predominant form of head and neck cancer in the United States. The survival rate for OPSCC is very high, which, while fortunate, yields many patients who are ... -
Improving Scalability of Trapped-Ion Quantum Computers Using Gate-Level Techniques
(2023)Trapped ions provide a promising platform to build a practical quantum computer. Scaling the high performance of small systems to longer ion chains is a technical endeavor that benefits from both better hardware system design ... -
Manipulating small model animals and biological nanoparticles via acoustofluidics
(2022)As rapid developments in technology merge acoustics and microfluidics, acoustofluidic technology has been increasingly employed in biophysical and biomedical research to address various challenges, especially in the fields ... -
Metasurface Apertures for Wireless Power Transfer and Computational Imaging
(2019)Metasurface apertures provide an alternative approach to the very commonly used phased arrays or electronic scanned antennas (ESA) for wireless power transfer (WPT) and imaging applications. Array antennas use radiating ... -
On Exponentially Localized Wannier Functions in Non-Periodic Insulators
(2021)Exponentially localized Wannier functions (ELWFs) are an orthogonal basis for the low energy states of a material consisting of functions which decay exponentially quickly in space. When a material is insulating and periodic, ... -
Techniques to Improve Gynecological High-Dose-Rate Brachytherapy Treatments
(2019)The thesis has two parts. The first project relates to real time dosimetry in Gynecological (GYN) High Dose Rate (HDR) Brachytherapy Treatments and the second part investigates a new workflow for Image Guided Brachytherapy ... -
Validation of the dosimetry for a Lay-down Total Skin Irradiation techniques by Monte Carlo Simulation
(2019)Total skin irradiation (TSI) with electron beam has been very effective for patient with Mycosis fungoides. We recently developed and implemented a technique of laying down position for patients who are too frail for the ...
