Image Transmission And Processing, For The Based On Dicom Standard

On view of integrality of medicine diagnosis and science study , many diagnosis image in clinic from patient study is produced by special instrument depended on computer. These kinds of images must include detailed information about patient, study and other relative; these information should be encoded and stored in coherent format and terminology.With the fast development of the Internet in the global, many text, image and audio informations can be transformed quickly and efficiently on internet Medicine image (including audio), as the important evidence clinic diagnosis and necessary shared resource for medicine research., can be transformed on internet,which will be a great improvement in medicine field. It is a new application of Internet. Medicine digital image communication is a new cross-subject based on computer network and medicine. DICOM(Digital Imaging Communication in Medicine ) is a typical symbol of the two subjects, which' is a synthetic application of computer, network, digital signal processing ,store technology.Content of recently DICOM standard is very complicated After studying each chapter and analyzing the architecture and core technology in the standard, this article offers a new method to master the standard from two aspects. First, Criterion for definition of object studied, including content, format, encoding of medical image. All these are the primary content of image communication and evidence of clinic diagnosis. Second, communication of object, including two ways depended on network communication and removable media. The former is a new application-layer protocol -DICOM Upper Layer based on TCP/DP , including format of transformed information, message state transfer, negotiation of association. The latter is storage service class including method of file operation, file format and media specification. This article describes a full structure of DICOM.Beginning with the current satiations of net medicine, according as conformance statement of DICOM standard , adopting oriented-object method ,this article implements the followings : DICOM Storage Service, including SCU and SCP.for many image type. Reshowing of high grayscale image, Encoding Process 1- baseline and JPEG-LS algorithm for compression and decompression of image. Farther study the print meta service class and the complicated procedure.
