New support system using a mobile device for diagnostic image display and treatment of acute stroke in Japanese depopulated areas

Stroke is the main cause of deterioration of activity of daily living in Japan. The social problem in Japan is the difference in medical quality between the urban and depopulated areas. To improve the problem, telemedicine using a mobile device between general physicians and stroke specialists became important with the increasing demand for rapid and correct diagnosis for treatment of acute stroke. We developed a system for rapidly exchanging diagnostic images and clinical information in depopulated areas to develop the standard thrombolytic therapy using alteplase for acute ischemic stroke [1,2].
