This federal Project Grant award from the National Institute of Biomedical Imaging and Bioengineering (NIBIB) under CFDA 93.286 "Discovery and Applied Research for Technological Innovations to Improve Human Health" provides $417,837 to the University of Texas at Austin to develop a new computational framework and specialized antenna arrays to enhance 3D electromagnetic (EM) imaging capabilities.

The key products and services to be delivered through this 24-month award include:

  1. Formulating computational frameworks to reconstruct 3D permittivity from non-invasive microwave scattering measurements, leveraging big data computing, optimization-based methods, and machine learning to model microwave scattering through biological tissue.
  2. Developing specialized antenna arrays with elements positioned at ultra-high densities or optimized non-regular spacings to collect microwave scattering measurements that can enable accurate 3D permittivity reconstruction with fewer measurements.

The utility of this new EM imaging approach will be demonstrated through application-oriented testing for differentiating stroke types and detecting/monitoring breast cancer. This project aims to enable high-resolution EM imaging with accurate lesion size and shape localization to support the clinical translation of EM imaging for diverse medical applications.

The University of Texas at Austin has also issued a sub-award to the Royal Institution for the Advancement of Learning / McGill University Office of Sponsored Research Division to contribute to this project.
