Non-invasive electromagnetic technique for monitoring time-trends of physiological changes at a particular location in the brain |
摘要 |
An apparatus and method for non-invasively sensing physiological changes in the brain is disclosed. The apparatus and method uses an electromagnetic field to measure localized impedance changes in brain matter and fluid. The apparatus and method has particular application in providing time-trend measurements of the process of brain edema associated with head trauma.
