Development Of Dose Conversion Coefficients For Radionuclides Produced In Spallation Neutron Sources, 2011 University of Nevada, Las Vegas
Development Of Dose Conversion Coefficients For Radionuclides Produced In Spallation Neutron Sources, Phillip W. Patton
Transmutation Sciences Physics (TRP)
A research consortium comprised of representatives from several universities and national laboratories will be established as part of this project to generate internal and external dose conversion coefficients for radionuclides produced in spallation neutron sources. Information obtained from this multi-year study will be used to support the siting and licensing of future accelerator-driven nuclear initiatives within the U.S. Department of Energy complex, including the Spallation Neutron Source (SNS) and Accelerator Production of Tritium (APT) projects. Determination of these coefficients will also fill data gaps for several hundred radionuclides that exist in Federal Guidance Report (FGR) No. 11 and in Publications …

Effective marketing and education through outreach strategies are critical to guarantee uninsured but eligible children enroll and retain coverage in Children’s Health Insurance Programs, such as Florida KidCare. The implementation of effective outreach can eliminate enrollment barriers. The authors cite that the tools for innovative practices for effective outreach strategies include: personal contact and involvement with an outreach coalition.
Statistical Image Reconstruction For Quantitative Computed Tomography, 2011 Virginia Commonwealth University
Statistical Image Reconstruction For Quantitative Computed Tomography, Joshua Evans
Theses and Dissertations
Statistical iterative reconstruction (SIR) algorithms for x-ray computed tomography (CT) have the potential to reconstruct images with less noise and systematic error than the conventional filtered backprojection (FBP) algorithm. More accurate reconstruction algorithms are important for reducing imaging dose and for a wide range of quantitative CT applications. The work presented herein investigates some potential advantages of one such statistically motivated algorithm called Alternating Minimization (AM). A simulation study is used to compare the tradeoff between noise and resolution in images reconstructed with the AM and FBP algorithms. The AM algorithm is employed with an edge-preserving penalty function, which is …
Radiation Therapy Treatment Plan Optimization Accounting For Random And Systematic Patient Setup Uncertainties, 2011 Virginia Commonwealth University
Radiation Therapy Treatment Plan Optimization Accounting For Random And Systematic Patient Setup Uncertainties, Joseph Moore
Theses and Dissertations
External-beam radiotherapy is one of the primary methods for treating cancer. Typically a radiotherapy treatment course consists of radiation delivered to the patient in multiple daily treatment fractions over 6-8 weeks. Each fraction requires the patient to be aligned with the image acquired before the treatment course used in treatment planning. Unfortunately, patient alignment is not perfect and results in residual errors in patient setup. The standard technique for dealing with errors in patient setup is to expand the volume of the target by some margin to ensure the target receives the planned dose in the presence of setup errors. …
Characterization Of A Blast Wave Device And Blast Wave Induced Traumatic Brain Injury In A Rat Model By Magnetic Resonance Imaging And Spectroscopy, 2011 Virginia Commonwealth University
Characterization Of A Blast Wave Device And Blast Wave Induced Traumatic Brain Injury In A Rat Model By Magnetic Resonance Imaging And Spectroscopy, Frank Corwin
Theses and Dissertations
Blast wave induced traumatic brain injury (bTBI) is a modality of injury that has come into prominence at the current time due to the large number of military and civilian personnel who have experienced the localized shock wave produced by explosive devices. The shock wave will travel concentrically outward from the explosive center, being absorbed and transmitted thru soft objects, such as tissue, and reflecting off stationary obstructions. Transmission and absorption in tissues can result in a number of physiological measureable injuries, the most common of which being what is frequently called “blast lung”. Blast lung involves the spalling effect …
Brachytherapy Seed And Applicator Localization Via Iterative Forward Projection Matching Algorithm Using Digital X-Ray Projections, 2010 Virginia Commonwealth University

Theses and Dissertations
Interstitial and intracavitary brachytherapy plays an essential role in management of several malignancies. However, the achievable accuracy of brachytherapy treatment for prostate and cervical cancer is limited due to the lack of intraoperative planning and adaptive replanning. A major problem in implementing TRUS-based intraoperative planning is an inability of TRUS to accurately localize individual seed poses (positions and orientations) relative to the prostate volume during or after the implantation. For the locally advanced cervical cancer patient, manual drawing of the source positions on orthogonal films can not localize the full 3D intracavitary brachytherapy (ICB) applicator geometry. A new iterative forward …

Adaptive Radiation Therapy Of Prostate Cancer, 2010 Wayne State University
Adaptive Radiation Therapy Of Prostate Cancer, Ning Wen
Wayne State University Dissertations
ART is a close-loop feedback algorithm which evaluates the organ deformation and motion right before the treatment and takes into account dose delivery variation daily to compensate for the difference between planned and delivered dose. It also has potential to allow further dose escalation and margin reduction to improve the clinical outcome. This retrospective study evaluated ART for prostate cancer treatment and radiobiological consequences. An IRB approved protocol has been used to evaluate actual dose delivery of patients with prostate cancer undergoing treatment with daily CBCT.
The dose from CBCT was measured in phantom using TLD and ion chamber techniques …
