Intracranial hemorrhage alters scalp potential distribution in bioimpedance cerebral monitoring: Preliminary results from FEM simulation on a realistic head model and human subjects

Abstract: Purpose: Current diagnostic neuroimaging for detection of intracranial hemorrhage (ICH) is limited to fixed scanners requiring patient transport and extensive infrastructure support. ICH diagnosis would therefore benefit from a portable diagnostic technology, such as electrical bioimpedance (EBI). Through simulations and patient observation, the authors assessed the influence of unilateral ICH hematomas on quasisymmetric scalp potential distributions in order to establish the feasibility of EBI technology as a… Show more

“…Nonetheless, they suffer from poor imaging resolution (about 10% of the subject diameter for EIT1011 and around 2.5 cm for MIT12). Although recently reported portable electromagnetic induction based sensing system16 demonstrates potential non-invasiveness and ease of operation over other sensing methods1718, it lacks the rigorous study of physiological significance for proper understanding of the measurements. However, clinicians prefer imaging over sensing in order to detect, locate and understand the profoundness of intracranial hematoma for proper medical diagnosis9101112131415161718.…”
