Researcher | Research Overview
Dr. Yetisir’s research focuses on the numerical modeling and optimization of electromagnetic fields to assess and improve safety and imaging for fetal MRI. Her research aims to better understand RF safety during fetal/placental MRI, enable more personalized imaging by developing patient-specific safety management tools and explore ways of decreasing tissue heating during MRI to allow faster imaging, reduce fetal motion artifacts and imaging cost, and increase patient comfort. Dr. Yetisir's research interests include modeling realistic fetal motion and radiofrequency (RF) exposure in the safety assessment of fetal MRI, using parallel RF transmission technology to mitigate dielectric shading and increase imaging speed during fetal MRI, comparing fetal and maternal local tissue heating during 3 Tesla and 1.5 Tesla MRI, and developing a novel pregnancy specific thermal simulator.
Researcher | Research Background
Dr. Yetisir completed her undergraduate studies in the Department of Electrical and Electronics Engineering at Bilkent University, Turkey in 2011. She completed her MSc and PhD in the Department of Electrical Engineering and Computer Science at Massachusetts Institute of Technology in 2014 and 2017. She was the recipient of Merrill Lynch Fellowship at MIT. During her time at MIT, Dr. Yetisir focused on developing methods to effectively and safely use parallel radiofrequency (RF) transmission to mitigate dielectric shading and tissue heating for adult brain MRI at 7T. She joined Fetal Neonatal Neuroimaging and Developmental Science Center at Boston Children’s Hospital as a postdoctoral research fellow in 2017. Since then, Dr. Yetisir has been working on optimizing RF safety, image quality and imaging speed of fetal/placental MRI.
