The Design And Implementation Of Information Object And Communication Model Based On DICOM

With the development of visual and network technology, the role of medial image information in clinical diagnosis, teaching and researching aspects is becoming clearer and clearer. Relative technology and system research have become one of the focuses in the present digital image fields. PACS (Picture Archiving and Communication Systems) as the important part of realizing medical image information management can digitize the data from the collection, display, storage, exchange and output of medical images. One of the technology problems that PACS has to solve is to unify all kinds of image formats from different image equipments and data communication standards. As a result, a new standard, named Digital Imaging and Communication in Medicine (DICOM), was born.It provides an open data-exchange standard and makes it possible to unify the storage and communication of images produced by different equipmentsContent 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. In the domain of criterion for definition of information object studied, including content, format, encoding of medical image. All these are the primary content of image communication and evidence of clinic diagnosis. And the communication of Medical Digital Image, which is based on TCP/IP. Based on the communication criterion, Four services:C-STORE, C-FIND, C-MOVE, C-GET are implemented with windows/Linux fashion.In addition, the applications such as information explorer, image compressor and format converter are developed in this paper. Furthermore, these applications have been used in laboratory projects with good with satisfactory results.
