Research of IHE-ITI-PIX Architecture Based on SOA System

Abstract

Based on the specification model of PIX (Patient Identifier Cross-reference) in the architecture of the IHE-ITI (Integrating the Healthcare Enterprise-IT Infrastructure), combining with SOA (Service-Oriented Architecture) architecture, the paper points out the method of patient information interoperability between heterogeneous systems. With standardized middleware as an information carrier of architecture platform of medical information, using SOA-based Web Service technology, the interoperability of patient information between medical institutions can be achieved.
