Abstract

There is a need for sending X-ray images from a mobile medical unit to a central computer. This transfer must be automatic and fast. Effective transfer of the X-ray images and other medical data from the medical vehicle or outpost must be possible. The system must be simple to use and the transfer method must allow the use of data on the central computer. Therefore a network connection is used. Cellular technology can be used to create such a data channel. Although the cellular spectrum is primarily used for telephone conversations, data transfer (computer files) is also possible. Cellular operators predict that data transfer will increasingly use more of the cellular spectrum. If a network link is made by means of a cellular telephone and modem, it is possible for the mobile unit to gain access to data on the central computer. The X-ray images are compressed to reduce transmission time. X-ray images can be sent with the aid of a cellular- or other telephone interface with a modem, by establishing a TCPIIP link between two computers on their RS232 ports. By using a network link, the transfer of the compressed images is reliable and adaptable. The study that was made shows the reasons for choosing TCP/IP as a network protocol. The TCP/IP Internet Protocol became the standard for the interconnection of computer systems. The TCP/IP Internet Protocol is more widely used througout the world than any other protocol. This ensures a great deal of compatability between network systems. Research- and educational institutions use TCP/IP as the primary basis for data communications. TCP/IP is referred to as the Internet Protocol series because it has the ability to ensure that systems that are connected to different types of networks can communicate.
