Potential For High Resolution Microscintigraphy Using Polycapillary Optics, Patrick Richard Conlon
Potential For High Resolution Microscintigraphy Using Polycapillary Optics, Patrick Richard Conlon
Legacy Theses & Dissertations (2009 - 2024)
Scintigraphy, also known as nuclear imaging, is the process of imaging an object that has been labeled with a radioactive material. A novel technique employing polycapillary optics for very high - resolution scintigraphy is presented. The small channel size and angular selectivity of polycapillary optics allow them to act as multiple-hole collimators and be used with high - resolution detectors. The ability of the optics to work with high resolution detectors allow the system to discriminate against scatter, thus negating the need for energy sensitive detectors, which are known to have poor resolution. Therefore the use of polycapillary optics presents …
Augmenting Program Data With Secondary Data Sources To Improve The Quality Of Existing Statistics : Four Examples From The New York State Department Of Health Hospital-Acquired Infection Reporting Program, Valerie Benson Haley
Legacy Theses & Dissertations (2009 - 2024)
The objective of this dissertation is to illustrate the novel application of methods that can be used to improve the accuracy of hospital-acquired infection (HAI) rates. Public reporting of HAI rates is relatively new. New York was one of the first states to mandate reporting in acute care hospitals (2007), followed by national pay-for-reporting in 2011, and national value-based purchasing in 2013. Given the financial ramifications of public reporting, it is critical that the data are validated and adjusted for differences in underlying risk among patient populations so that hospital performance can be fairly compared. However, limited information on the …
Assessment Of Human Exposure To Perchlorate And Perfluoroalkyl Substances In The United States : Biomonitoring And Environmental Monitoring Approaches, Qian Wu
Legacy Theses & Dissertations (2009 - 2024)
Perchlorate is an oxidant in solid fuels and explosives and is produced in large quantities worldwide. Perchlorate is a ubiquitous environmental contaminant and is present in water, food, indoor environment and humans. Human exposure to perchlorate is a concern due to its ability to disrupt the thyroid gland functions.
