This Project Grant award from the National Institute of Biomedical Imaging and Bioengineering (CFDA 93.286 - Discovery and Applied Research for Technological Innovations to Improve Human Health) provides $117,507 to New York University School of Medicine to develop a novel, rapid, and memory-efficient open-source software for radiofrequency (RF) coil modeling in magnetic resonance imaging (MRI). The project aims to create an electromagnetic simulation tool that can optimize the design of RF coils for ultra-high field (>3T) MRI scanners, which is critical for enhancing image quality and patient safety at these higher field strengths. Key aspects of the work include developing a domain decomposition method for modeling EM interactions between RF coils and biological tissue, implementing a RF circuit simulator for coil tuning and matching, and validating the software's accuracy, speed, and memory efficiency compared to commercial packages. The software will be compatible with any MRI frequency and anatomical region without the need for expensive licenses. The project will culminate in the design, optimization, and construction of a novel 7T coil for prostate imaging. This award supports a "Pathway to Independence" for the principal investigator, Dr. Ilias Giannakopoulos, to transition to an independent faculty position in radiology or biomedical engineering.
