Noninvasive and portable stroke type discrimination and progress monitoring based on a multichannel microwave transmitting–receiving system
Abstract The hemorrhagic and the ischemic types of stroke have similar symptoms in the early stage, but their treatments are completely different. The timely and effective discrimination of the two types of stroke can considerable improve the patients' prognosis. In this paper, a 16-channel and...
