Comprehensive Study on Dielectric Properties of Rat Brain Tissue Following an Ischemic Stroke at 0.5-10 GHz.
Stroke happens when a blood vessel in the brain, is blocked by a clot (ischemic stroke) or bleed due to a vessel rupture (hemorrhagic stroke). The dielectric properties of healthy brain tissue are different from the one that is affected by stroke. In this study, these properties are measured in rat’s brain by an electromagnetic probe at frequency range 0.5-10 GHz. Subsequently, the changes are related to the type and level of brain injuries. One of the applications of this research is early diagnosis of different types of stroke and traumatic brain injuries by electromagnetic imaging that significantly impacts the effectiveness of the treatment.
