This study details a large-scale Picture Archiving and Communication System (PACS) implemented in a clinical setting. The system integrates various imaging modalities and information systems, enabling digital radiology workflows and future research into system performance and cost-effectiveness.

Area of Science:

  • Medical Imaging
  • Radiology Informatics
  • Health Information Systems

Background:

  • Traditional film-based radiology workflows present challenges in image management and accessibility.
  • The development of Picture Archiving and Communication Systems (PACS) aims to digitize radiological processes.
  • Previous PACS research highlighted the need to evaluate system performance and cost-effectiveness.

Purpose of the Study:

  • To describe the implementation of a large-scale Picture Archiving and Communication System (PACS) in a clinical environment.
  • To integrate the PACS with existing hospital and radiology information systems.
  • To establish a platform for investigating system performance and cost-effectiveness of digital versus film-based systems.

Main Methods:

  • Deployment of a comprehensive PACS infrastructure including controllers, database management, networks, and optical disk archive.

  • Integration with multiple imaging modalities: 3 MR, 4 CT, 3 computed radiography, and 2 laser film digitizers.
  • Connection to seven round-the-clock display stations across various clinical departments and one laser film printer.

    • Main Results:

    • The PACS has been operational since February 1992, archiving an average of 2.0 gigabytes of image data per workday.
    • System performance data for various components over a 3-month period were tabulated.
    • The system is actively used by radiologists, fellows, residents, and clinicians for case review, conferences, and primary diagnosis.

    Conclusions:

    • The implementation of this large-scale PACS represents a significant advancement in PACS research and development.
    • The integrated digital system facilitates daily radiology practice, improving access to medical images.
    • The established PACS infrastructure will enable critical investigations into system performance and cost-effectiveness compared to film-based systems.
