With a view to providing paramedical care within moving vehicles, a telemedicine technique using mobile satellite communication was proposed. With this technique, the diagnosis from a specialist and the emergency care under his/her instructions would be available on the spot without unnecessary delay. The characteristic problems of this technique were identified as: channel capacity, size of the system, reliability of vital sign transmission, real-time operation and electromagnetic interference. Measures against these problems were devised, and their effectiveness was analyzed. A data format was designed and an experimental system was developed. The system can simultaneously transmit a color image, an audio signal, 3 channels ECG and blood pressures from a mobile station to a ground station. It can transmit an audio signal and error control signals from a ground station to a mobile station in a full duplex mode. Fundamental transmission characteristics were measured in a fixed station. Finally, experiments of medical data transmission were conducted with a navigating ship and an aircraft flying an international route. The measured threshold values of C/N(o) to guarantee satisfactory data reception were well below the lower boundary of C/N(o) of the communication link. Consequently, the feasibility of this technique was verified.
为了在移动车辆内提供辅助医疗护理，提出了一种使用移动卫星通信的远程医疗技术。利用该技术，无需不必要的延迟，即可在现场获得专家的诊断及其指导下的紧急护理。该技术的典型问题被确定为：信道容量、系统规模、生命体征传输的可靠性、实时操作和电磁干扰。针对这些问题制定了措施，并分析了其有效性。设计了一种数据格式并开发了一个实验系统。该系统可以同时从移动站向地面站传输彩色图像、音频信号、3通道心电图和血压。它可以以全双工模式从地面站向移动站传输音频信号和差错控制信号。在固定站测量了基本传输特性。最后，在一艘航行船舶和一架飞行国际航线的飞机上进行了医疗数据传输实验。为保证满意的数据接收而测量的C/N(o)阈值远低于通信链路C/N(o)的下限。因此，验证了该技术的可行性。
