How about using communication technology in telemedicine

Through satellite and integrated services data network (ISDN), in teleconsultation, teleconsultation, long-distance transmission of medical images, teleconferencing and military medicine. Two-way audio-visual communication technology, wired, wireless and satellite communications, the application of different purposes and needs, the equipment configured in the telemedicine system and the use of communication network environment also varies. The telemedicine diagnostic system is mainly configured with a variety of digitized medical instruments and corresponding communication interfaces, and operates mainly on a local area network (LAN) within the hospital. End-user devices include electronic scanners, digital cameras, and microphones and speakers.

Communication Technology

(1) Network Interface. Different telemedicine needs and communication environments have a variety of choices for communication networks, so there are high and low network interface rates. (2) Network protocol. ATM (Asynchronous Transfer Mode) interconnection protocol is widely used in telemedicine systems. H.324 videoconferencing protocol can be used for transmitting medical images over the telephone network.TCP/IP protocol can be used for LAN and WAN interfaces, with which medical images and remote medical information sources are accessed. (3) Video transmission. According to different telemedicine needs, the video transmission rate is different, which can be roughly categorized into two types: low rate and high rate transmission; the former is used for videoconferencing, while the latter is used for transmission of diagnostic videos. (4) Audio transmission. In addition to video, there is also audio transmission within the telemedicine system, which can also be categorized into low-rate and high-speed transmission, with the former being used for consulting sessions and the latter for diagnosing conditions. (5) Still image (film) transmission. Usually, the transmission of static images (slices) is a unidirectional communication, the transmission rate is calculated in terms of a single frame, and the traffic is bursty. (6) Medical record file. It is also a unidirectional transmission and is mainly textual information, so the transmission bandwidth requirement is not high. (7) Backbone network. There are a number of options available as a backbone network for telemedicine, but as the network expands, it is necessary to interconnect individual LANs into a WAN via bridges or routers.
