The Impact Of Temporal Resolution On Clinical Decision-Making For Individuals With Dysphagia, Shauna Corinne Murray

Speech and Hearing Sciences ETDs

INTRODUCTION: Dysphagia, or a disordered swallow, affects up to 1 in 25 individuals in the United States. The gold standard for assessing dysphagia is the videofluoroscopic evaluation of swallowing (VFES). This allows the clinician to observe the swallow anatomy in motion via an X-ray movie, which historically was recorded at 30 frames per second. In recent years VFES have been performed at less frames per second due to radiation concern. This project investigates the effect of using lower temporal resolutions on assessment of video-fluoroscopic swallow studies.

METHODS: In this investigation, 30 swallow studies, all acquired at 30 frames per second, …

The Air Gap Effect Between A Bolus And The Skin Surface For Chest Wall Irradiation, Marisa Clark

Culminating Experience Projects

Planning technique and bolus choice are important aspects in planning chest wall irradiation (CWI). Many previous studies have tested various combinations of photon energies, electron energies, bolus types and sizes, air gaps sizes, and treatment methods. This study aims to assess the effect of smaller, clinically relevant air gap sizes on specific chest wall treatments using a variety of common bolus types. Due to the Covid-19 pandemic, no data was able to be collected and was instead fabricated by the researcher. Four different treatment plans were created on a phantom patient using various energies of photons (6MV and 10MV) and …
