The majority of the world's coral reefs are in various stages of decline. While a suite of disturbances (overfishing, eutrophication, and global climate change) have been identified, the mechanism(s) of reef system decline remain elusive. Increased microbial and viral loading with higher percentages of opportunistic and specific microbial pathogens have(More)
PURPOSE To evaluate the dosimetric effect of various clinically used bolus materials. METHODS Materials investigated include solid water, superflab, wet gauze, wet sheets, Play-Doh™ , and gauze embedded with petroleum jelly. Each bolusing material was scanned in a Philips CT to determine the Hounsfield unit (HU) and to verify uniformity throughout the(More)
PURPOSE Advanced treatment delivery techniques require more robust treatment planning system (TPS) models for accurate dose planning and computation. As stereotactic body radiation therapy (SBRT) and volumetric-modulated arc therapy (VMAT) treatments become more prevalent, the ability of the TPS to accurately calculate dose delivered from small fields(More)
The demonstration of nurses' competency has been a challenge for nurse educators for a multitude of reasons. Standardizing competencies across a health care system is especially challenging. One multihospital health care system embarked on a journey to standardize and implement competencies across the system. Using a collaborative approach, the Wright model(More)
A robust algorithm is presented for labeling rows and columns in an irregular array. The algorithm is based on hierarchical pattern matching to a local lattice, which is used as a template. Starting from the best local match, the pattern is expanded hierarchically to encompass the entire array. An application to labeling digitized images of an array of(More)
PURPOSE To assess RadCalc as a means for analyzing fluence maps of IMRT QA patient plans. Eclipse generated fluence maps were compared to RadCalc fluence maps generated from both Eclipse parameters and from dynalog trajectory files. METHODS Six IMRT plans consisting of fifty individual fields were compared both field-by-field and as composite plans. These(More)

PURPOSE There are multiple factors that have lead to the need for an increased precision and accuracy in Radiation Therapy. The increased use of IMRT and SBRT with hypofractionated doses requires optimal precision and accuracy in aligning the treatment delivery with the target. Recent advances in imaging and motion management of patients during the(More)
