BREIT: Derived Data and Pretrained Models for Brain Stroke Reconstruction with Multi-Frequency 3D EIT

Data and model release for BREIT, a framework for brain stroke reconstruction using multi-frequency 3D Electrical Impedance Tomography. This record includes BREIT derived head/tissue geometry tetrahedral element-wise data for ISLES-derived ischemic stroke cases, IXI-derived healthy controls, synthetic physiological cases, and derived UCLH patient geometries, as well as pretrained DeepDbar and dFNOBAR/FNO-U-Net cascade checkpoints. The release supports regeneration of forward EIT simulations, D-bar caches, and reconstruction experiments.
