腦血管疾病在國人死因中高居第三，其中最常見的就是腦中風。腦中風可分為缺血性腦中風及出血性腦中風，其中缺血性腦中風(腦梗塞)是目前最常見的中風型態，在腦梗塞早期，僅只有病變的中心血管床部位壞死，但是到後期可能會影響梗死周圍的組織功能，因此透過「早期」中風血管特性的偵測，可能有助於提供腦部循環資訊。這有助於治療的開始，甚至有助於早期的預防指標開發。

Cerebrovascular disease was the third highest cause of death in Taiwan, which the most common was stroke. Stroke can be divided into ischemic stroke and hemorrhagic stroke, ischemic stroke (infarction) is the most common of stroke. In the early infarction, only the lesion in the center of the vascular were necrosis, and in late period may affect the function, which surround of infarcted tissue.
