Microwave helmet detect stroke
Scientists have developed a special helmet, which can quickly determine whether a patient has a stroke and what causes it. Swedish scientists have invented a device that is intended to be used primarily in emergency situations. Conduct a preliminary test of the ambulance crew. If stroke physicians should react very quickly. If treatment is not started within 4 hours after a stroke, some parts of the brain may begin to die. In order to offer the best treatment, doctors must first determine whether the bleeding stroke or blood clot that blocks blood flow.
Computed tomography (CT) can show it, but the organization of such an investigation will take some time. To expedite the process, the Swedish researchers from Chalmers University of Technology (Chalmers University of Technology) and come up with a mobile device, allowing to determine the cause of stroke. Helmet uses microwave signals (as in a microwave oven ) and a smartphone allows you to create a picture of what is happening in all parts of the brain. tests prototype helmet made of bicycle helmets, showed that he can fairly accurately determine the difference between hemorrhagic and ischemic stroke, although and in 100% of cases. According to experts, they still have quite a lot of testing, but the invention can be very useful in the future.
