Research And Implementation Of PACS Workflow Based On IHE

With the enhancement and extending of DICOM (Digital imaging and Commumcations in Medical), PACS (Picture Achieving and Communication System) projects was widely implemented and carried out all over the world. In the area of system putting in practice, because of complexity of actual workflow and system environment, the technology had been asked for higher level requirement, and supported more advanced features. From framework of integration of system, to industry standards, to application used, design and research of PACS was deepened and innovated along with the time.According to the situation mentioned above, many research institutes and industry organizes relating to PACS, had carried out a new circle of research and upgrade of constitution of the standards and system integration. These organizes and their standards were ACR-NEMA (American Colleague of Radiography - Nation Electrical Manufacturers Association) DICOM, RSNA (Radiological Society of North America), RSNA (Radiological Society of North America) and HIMSS (Healthcare Information and Management Systems Society)'s IHE (Integrating the Healthcare Enterprise), and HL7 (Health Level Seven) which was assigned as the industry standard of ANSI (American National Standards Institute). The same features of these standards and protocols lately added includes that they define and plan the system workflow and information sharing between heterogeneous systems. Through these methods, we could resolve the problem of actual workflow and system integration in healthcare region, and then we could get better application results.We discussed and compared the workflows of the periods before PACS and original of PACS at first. Then based on parsing of criterion and standards, we designed the framework of PACS workflow based on the IHE technique criterion. After that, we parsed the concrete content relating to workflow in the standards, and implement them using various technology. Under the framework, the detailed system analysis and implementations were separated into three parts. The first part analyzed and implemented the workflow sourced from standard DICOM modalities. The second part analyzed and implemented the workflow sourced from non-standard DICOMmodalities. The third part designed the subsystem of PACS management in order to manage wholly. By these means, we could upgrade the research and integration development of PACS to a higher level, and we could realize the object of advance hospital's healthcare quality on full-scale and reduce the general cost.
