OpenRIMS: an open architecture radiology informatics Management system

Area of Science:

• Medical Informatics
• Radiology Information Systems

Background:

• Traditional Picture Archiving and Communication System/Radiology Information System (PACS/RIS) archives can be costly and prone to data inconsistencies.
• Developing integrated PACS/RIS archives using open-source tools presents an opportunity for cost reduction and improved data management.

Purpose of the Study:

• To present the benefits and architecture of an integrated PACS/RIS archive developed using open-source tools and methods.
• To demonstrate a model system capable of managing radiology workflows from order entry to data archiving and retrieval.

Main Methods:

• Developed a multitiered architecture utilizing a single database with an open database connectivity bridge.
• Integrated a Linux server supporting Health Level 7 (HL7), Digital Imaging and Communications in Medicine (DICOM), and HTTP connections.
• Implemented a web-based user interface for human interaction and HL7/DICOM links for informatics system communication.

Main Results:

• The system architecture supports order acceptance, exam scheduling, DICOM worklist provision, study archiving, and DICOM query/retrieve.
• Key components including the database schema and web user interface are complete.
• The system demonstrates reduced risk of redundant and inconsistent data, with potential for standardized data mining tools.

Conclusions:

• An open-source PACS/RIS archive offers significant advantages, including cost-effectiveness and enhanced data integrity.
• The developed model system provides a robust framework for integrated radiology workflow management.
• Further development is ongoing to refine the DICOM/HL7 interface and complete DICOM service classes.
