    In this study EIT was used to monitor brain impedance changes due to variations in cerebral fluid content during dehydration treatment of edema patients. 30 patients with cerebral edema were continuously imaged for two hours after the initiation of dehydration treatment. Results show that overall impedance across the brain increased significantly 5 minutes after dehydration treatment started. And different brain tissues have different reactions towards dehydration.

    According CT images, a 3D abdominal bleeding simulation model with real shape was set up using COMOSOL Multi-physics. By parameter sweeping, the surface measurement data for EIT were obtained while bleeding from 0~800ml. Total relative changes (TRC) of the data were calculated, shown a linear correlation (R>0.99) with bleeding volume (BV), which implies TRC be a good quantitative index to indicate BV.
