This study explores the architecture of a central storage facility for a hospital Picture Archive and Communication System (PACS). Prefetching images is crucial for optimal PACS performance, enabling efficient daily storage and retrieval of medical imaging data.

Area of Science:

  • Medical Imaging Informatics
  • Computer Science Applications
  • Health Information Systems

Background:

  • Hospitals require robust Picture Archive and Communication Systems (PACS) for managing medical images.
  • Existing PACS architectures face challenges in efficiently handling large volumes of imaging data and concurrent user activities.

Purpose of the Study:

  • To investigate the architecture of a central storage facility for hospital PACS.
  • To propose and evaluate an implementation for efficient PACS data management.
  • To assess the impact of prefetching strategies on PACS performance.

Main Methods:

  • Architectural study of a central storage facility for PACS.
  • Development and simulation of proposed PACS storage implementations.

  • Evaluation of system throughput for storing and accessing medical image sets.

    • Main Results:

    • The proposed central storage facility architecture is feasible and can store over 500 image sets daily.
    • Prefetching, especially with pipelined systems, significantly enhances PACS performance.
    • The system can handle simultaneous storage, review, and output activities efficiently.
    • The proposed architecture can be realized using readily available equipment.

    Conclusions:

    • Prefetching is essential for achieving good performance in PACS.
    • The proposed central storage facility design meets the demands of a busy hospital PACS.
    • The study demonstrates the viability of current technology for advanced PACS implementation.
