Aspects of Information Communications Technology for Better Medical Control

The 3G mobile phone has propagation problems in urban areas and experiences severe congestion after major disasters in supporting mobile eHealth. We expect a Quasi-zenith satellite with nationwide coverage. In near future, the data transmission of image of pharygoscopy, motion picture of light reflex, 12-leads ECG, automated ultrasonic echo and vital signs from ambulances shall be performed to assist medical control. For example, Thrombolytic agents are reportedly effective even when injected into a vein, if injected in the early stages of acute myocardial infarction, which will reduce medical costs, resulting in high-quality services available uniformly across the nation. This paper describes Japanese aspects of mobile eHealth to support ambulatory applications.
