Implementation Of DICOM Service In Oral Imaging Equipment Console

DICOM(Digital Imaging and Communications in Medicine) is the standard made by ACR(American College of Radiology) and NEMA (National Electrical Manufactorers Association), used in digital medical image transmission, display and storage. In standard of DICOM defined images and related information defined the composition of the format and exchange method, using the standard, people may be established on a video equipment to complete the work that input/output images.Oral digital device have great business opportunity, The production factories are attaches great importance to the research, development and utilization, But because the international digital imaging equipment for oral domestic digital standard not fully establish uniform standard, each manufacturer production oral imaging equipment digital degree, interface each are not identical and not compatible. Oral digital imaging equipment in the clinical work in recent years, the development and utilization of more extensive digital X-ray tooth slice machine, digital X-ray panoramic machine and CT equipment to operate, because of its digital image files practical and systematic storage and retrieval characteristics such as general oral medical imaging equipment is irreplaceable superiority, obtained the general medical workers Praise in the clinical work. In practical work, because the above program about digital degree, interface and software and hospital HIS system, PACS system compatibility, how to management and utilization oral digital imaging equipment, is a headache problem for hospital manager. From the overall situation in hospital after weigh the pros and cons of digital equipment often only lower utilization degree or in an old work mode to carry out the daily work, digital imaging equipment such oral various superiority was greatly weakened even lost.Chinese oral medical equipment DICOM standardization work in infancy, most oral medical equipment is not implemented support DICOM standard, image storage transmission format and no realizes standardization, And oral Digital device support DICOM standard is the trend,our medical equipment development, production department all attaches great importance to the development trend. Therefore this paper based on the related theory of DICOM standard research, this paper expounds the oral X-ray imaging equipment DICOM Worklist service applications, oral image DICOM file storage and its design and realization process, research and development support DICOM standard oral X-ray imaging equipment control system, realize the digital oral image equipments.The Thesis content have two parts:the first is mostly DICOM standard related theory research, including the Worklist Modality information object and the attribute discusses and DICOM images file storage theory and the theory of information object expatiated; The second is DICOM service Application and coding realized in oral equipment console, Oral console DICOM basic work list server design and Development as well as oral image file format design and development of the object storage. The project design and coding, mainly discusses the realization of the oral equipment design organization forms of data flow and the corresponding coding, service object, to realize the function of SCU Worklist information object definition, and Worklist SCP send messages by C-FIND, realize PACS, sharing information between PACS\RIS and equipment, DICOM file storage of data sets, headers and image files architecture is generated.The Thesis mainly research process:first of all, according to the requirement analysis, dental hospital in order to solve the oral images equipment and hospital PACS system, RIS compatibility problems and oral image, the design gives DICOM standardized problem console work flowchart oral image equipments, Then detailed analysis of the function of each module in the flow chart and C++programming interface design, developing and realizing. Main algorithm design idea is based on DICOM Worklist information object standard definition, establish a connection with PACS/RIS, through the request information and check get patients query information from Worklist SCP Worklist SCU, patients get get PatientInfo relevant information, Oral imaging equipment console software received data exchange documents from Worklist SCU, Setting exposure parameters, location, quantity, etc,Then give oral imaging equipment to send exposure instruction and capture images, save image to Shared memory block, and output equipment and patient information affiliated attribute. Then sends a Windows broadcast message, the windows message's title may be updated, So that,the message catch by third-party software. Trigger the follow-up processing operation:read and analyze the Raw Data image Data and patient information, according to the DIOCM file format, RawData image is transformed into DICOM format images.Software development design uses the development tools is Microsoft Visual C++6.0.The Thesis analyzed the DICOM standards relevant theoretical knowledge, will study of relevant theoretical knowledge DICOM standards applied to the actual development project, design the oral X-Ray equipment console flow, Written in c+ +code programming realized all console process oral equipment used in the actual module, and the hospital equipment system in oral digital images, and achieved good effects of operation. Paper results in the oral digital device of kaiping center hospital get through the verification, and connect with the PACS (Develoment project of Guangzhou Lansign software.,Ld)This thesis mainly solved oral image equipment and hospital, HIS system of interface compatibility problem PACS system and DICOM standardized oral image problem, its solution algorithm design ideas to other imaging equipment interface problems and DICOM standardized medical image is important referential significance. In Kaiping Center Hospital, the normal operation of product is nearly a year, For practical value, to do some practical value of the research work in the digital oral imaging equipment, medical image DICOM standardization. The research of medical imaging technology has important significance,。The digital hospital management is the future development trends, and the image digitization is one of the most important parts of it. We hope that this paper discuss the design of digital images of domestic other medical equipment development be reference significance.This thesis specific layout is as follows:The first chapter is to introduce a standard, dicom history and scope of application, pacs system development, research and the main background papers and research.The second chapter to dicom, simply introduces dicom standard noun dicom 3.0, the standards of various components; detailed study on the third part, the fourth part of this paper comes to theory of knowledge:dicom information, models and information exchange network dicom news and communications, dicom the standard media file storage, dicom, data collection and data elements, etc.The third chapter Image equipment for oral console process, main will study of relevant theoretical knowledge DICOM standards applied to the actual development project, design the oral Image equipment console flow chart, detailed design flow chart and the function of each module and interface.The fourth chapter Worklist SCU oral equipment for console design, Detailed research on dental equipment console interface of software design, First defined Worklist information E/R model, DICOM Worklist SCU use C-FIND, running, request and response-analysis and design Worklist way of working and Modality Worklist attribute information object, defined Worklist Worklist service SOP kind, and the Worklist SCU interface design by C++code for the programming.The fifth chapter for oral image DICOM format storage design,详Detailed research on oral image DICOM format storage software design:Determining the Digital the oral Image Intea IOD as oral Image information, define the IOD prototype object of oral Image information object, build data set, analytical data sets, constructing the file header, collected through coding get system according to DICOM standard oral panoramic images stored the Image file, after the oral DICOM images using C++code format storage system for the programming.The sixth chapter is the summary and outlook. a summary of this paper work and the results of the papers into a follow-up study.
