This study introduces a component-based architecture for accessing medical images from Picture Archiving and Communication Systems (PACS) via web browsers. The developed system demonstrates comparable performance to traditional workstations, enhancing accessibility for various healthcare applications.

Area of Science:

  • Medical Imaging Informatics
  • Web Technologies in Healthcare
  • Radiology Information Systems

Background:

  • Picture Archiving and Communication Systems (PACS) are crucial for medical image distribution using Digital Imaging and Communications in Medicine (DICOM) protocols.
  • Numerous healthcare applications require access to PACS images, necessitating efficient and accessible image retrieval methods.
  • Existing diagnostic display software architectures and Web-based solutions have limitations in seamless PACS image integration.

Purpose of the Study:

  • To develop a component-based image display architecture for accessing and manipulating PACS DICOM images through web browsers.
  • To integrate this component into a web-based image distribution server, enabling easy access comparable to dedicated PACS workstations.
  • To evaluate the performance of the web-based system against traditional diagnostic workstations.
