Network / DICOM TCP/IP 网络结构 DICOM3.0 概论 PACS/RIS/HIS DICOM规格是一种电脑医学影像的通讯规格，它发展的主要目的，是为了要让医院中各色各样的医学影像仪器和软体间能够有一个共通的语言，以塑造一个无国界、无障碍的电脑化医学影像环境。 OSI layer model (1)Open Systems Interconnection OSI is defined as a model of 7 layered network protocol architecture by ISO. 1.Application layer 2.Presentation layer 3.Session layer 4.Transport layer 5.Network layer 6.Data Link layer 7.Physical layer manages addresses on network. translates between Application layer and Session layer. provides service. manages virtual connection (establishing / releasing). performs data compression, correction or so on. establishes physical communication line. defines hardware characteristics and requirements.
