Abstract

It is imprint for stimulating PACS markets that a standardization of the interfaces for each component of PACS are carried out so that venders can install own components on an individual basis. For on-line interfaces between imaging equipment, the ACR-MEMA standards were proposed in the United States and the MIPS standards will be proposed this year in Japan. These standards have the same seven step hierarchy as the OSI reference model. The presentation layer is specialized for medical imaging use. The physical layer has a 50-pin connector with a l6-bit parallel signal transmission protocol. Communication protocols are very complex system. However, it is important for PACS designers to understand it so they can estimate boundary condition of each component. Regarding the magnetic tape standards the JAMIC, MIPS and ACR-NEMA formats are available. The JAMIC format has actually been installed in several types of medical equipment. These formats may be selected according to the specifications of the system when it is difficult to use on-line interfaces. Standardization is only one step in constructing a multi-vender system. There are many differences between equipment of different venders. Methods of connect with RIS or HIS and abilities how fast or how often the equipment can transmit image data are different. For constructing a multi-vendor system, it is important to appoint a responsible system designer who can propose such specifications to the vendors of the components.
