Abstract:
Objective To build finite-element models of cerebral hemorrhage on which a simulation study of electrical impedance tomography(EIT) is based.Method With a kind of four-layer concentric circle model of head,finite-element method and dynamic NOSER algorithm are performed to reconstruct the images.Result As to the single-focus model of the cerebral hemorrhage,the focus can be clearly imaged,while to the several-focus model,the focuses can be imaged with vaguely adjacent boundaries.Conclusion The dynamic NOSER algorithm is an effective method to image cerebral hemorrhage in EIT.
