A Novel Approach for 2D Electromagnetic Imaging of Human Brain Based on ODIL

In this work, a novel 2D electromagnetic imaging approach for human brain is proposed based on the Optimizing a Discrete Loss (ODIL) framework. The finite element boundary integral (FEBI) method is employed for the accurate modeling of the electromagnetic field distribution inside the human brain model. Inspired by the ODIL framework, a discrete residual loss function is established and optimized to reconstruct the dielectric distribution of the 2D human brain model. Numerical experiments demonstrate that the proposed method exhibits good reconstruction accuracy and computational efficiency in 2D human brain electromagnetic imaging.
