Advancing Electromagnetics for Revolutionizing Biomedical Technology

Featuring Shaoying Huang, PhD, Singapore University of Technology and Design (SUTD)

February 12th, 2:00 pm – 3:00 pm at Jerome L. Greene Science Center

This talk will share how we advance electromagnetic (EM) solutions to revolutionize biomedical technology in the BioMedical-Electromagnetics Research Group led by Dr. Shaoying Huang in Singapore University of Technology and Design (SUTD) in Singapore.  The biomedical technology focused in this talk is magnetic resonance imaging (MRI). Three MRI-EM-related projects will be presented. First comes the recent progress on the development of a low-field man-portable MRI head imager.  The advancements on magnet designs, image reconstructions, radiofrequency (RF) coil designs, and the integration of different components will be introduced. This is an exploration of fundamental technologies and their integration towards a feasible portable MRI solution. It may pave the way for flexible MRI scans, which may enable studies that are not supported by existing MRI scanners, such as those on the correlation of brain and body movements that are difficult to conduct in a conventional scanning setup. Besides RF engineering and image reconstruction, moving from low field to high field, the development of a fast algorithm for high-field MRI safety will be shared. This study will show how the advancement of computational EM shed light into solving safety problems in a high-field MRI system. Moreover, stepping away from proton density, MRI as a probe to measure electrical properties of human tissue in vivo through manipulating Maxwell’s equations, which is named MR electrical property tomography (MREPT), will be detailed. It will illustrate the key role of EM to widen the horizon of what MRI can visualize. Besides MRI-related projects, an MR-inspired university-industry collaborative project on non-contact in-circuit testing (ICT) will be briefed. Our research vision is to further advance the frontier of both EM and biomedicine-related physics. Specifically, for high field MRI, to realize safe scans; for low-field MRI, to realize a more flexible and relatively low-cost MRI scanner that allows routine scans, even in a daily manner, to capture the time course of aging and other neurological diseases with different tissue contrasts, such as electrical properties besides proton density.
