"With encouragement from my mentor, I applied to the Scholars Program to pursue an interest in engineering in medicine. I anticipate that my laboratory work and research meetings will provide an opportunity to learn about medical physics and the nature of scientific investigation. I am excited to contribute to research that hopefully will improve the safety and efficiency of medical practice."

The Impact of Pediatric Anthropometric Patient-phantom Matching on Organ Doses During Interventional Fluoroscopic Procedures
Over the past decade, Dr. Bolch and his students in the UF Advanced Laboratory for Radiation Dosimetry Studies have been developing state-of-the-art computational tools for the assessment of internal organ doses received by patients undergoing diagnostic imaging and interventional treatments. One key advancement is the development of NURBS-based virtual hybrid phantoms, computerized representations of human anatomy. This study will investigate the effectiveness of pediatric patient-phantom matching in comparison with stylized reference phantoms for the purpose of dosimetric calculations. First, patient-specific phantoms will be constructed with the use of unmodified computed tomography images of pediatric patients obtained from Shands Jacksonville Radiology Department. The patient-specific phantoms represent an exact computational replica of the person providing the imaging data and will be constructed through segmentation with the use of 3D-Doctor, a vector-based 3D imaging and modeling software. The segmentation process will define the organs of interest for dosimetric calculations. Second, the patient-specific phantom will be imported as a polygon mesh into a computer animations software RHINOCEROS, where it is to be voxelized at a resolution of 2x2x2 cubic mm in preparation for skin and organ dose calculations with the use of Monte Carlo methods and an in-house skin dose calculation software. Last, a patient-dependent phantom from the UF library of computational phantoms, which most closely matches the patient-specific phantom, will be selected along with a stylized reference phantom to conduct the organ dose calculations. A cardiac projection (PA) will be simulated with both the skin dose and Monte Carlo software to assess differences in skin and organ doses for all phantoms. The effectiveness of the patient-dependent versus the stylized phantom will be quantified via absolute percent differences using the patient-specific dose conversion coefficients as the true value.
