The Design And Application Research Of Picture Archiving And Communication System Based On IHE

With the improvement of domestic medical system and further opening of medical market, the hospital information construction has been an important factor which affects the level of medical treatment, service quality and competition ability of hospital. Recently, HIS, LIS and RIS have been comprehensive applied by lots of hospitals, supporting the daily operation of hospital. However the application of PACS still can not be achieved, because of its data picture characteristic, which involves problems relating to the integration of diverse medical information.To achieve the exchange and share of medical data, some authoritative organizations have established a series of standards, such as HL7 and DICOM, and defined a frame: Integrating the Healthcare Enterprise (IHE), which based on these standards. With more and more equipment venders and system development corporations following these standards , the integration of PACS with other information systems and the share of information becomes possible.Through in-depth theory research of the content of HL7, DICOM, the information parsing mechanism, the communication model, the basal content of IHE, the communication mechanism of each integration model, we establish the theory foundation to design the multi-arrangement integration project for hospital.Through analyzing and evaluating the workflows of radiation department in different periods, holding the essential of workflow, we designed the new workflow frame based on IHE.Under the IHE frame, we designed the integration project from four lays: management, data, function, workflow, which has realized the medical data exchage. We evaluated the system predominance and benefits, for the purpose of guidance the development of system.This thesis analyzes the HL7, DICOM and IHE standards,combines with hospital management mode, proposes a schema for Full-PACS. This schema strictly follows DICOM3.0 standard,absorbs the design idea of IHE and carries out the patients- centered management idea.
