The DHCP Integrated Imaging System was updated from a DOS platform to modern workstations. An object-oriented approach enhanced software portability across different systems.

Area of Science:

  • Medical Informatics
  • Software Engineering

Background:

  • The DHCP Integrated Imaging System originally operated on a two-screen DOS-based MUMPS platform.
  • Modernization efforts required migrating the system to diverse workstation environments, including X Window and Microsoft Windows.

Purpose of the Study:

  • To describe the challenges and strategies involved in migrating the DHCP Integrated Imaging System to new platforms.
  • To detail the software design and development considerations for handling cross-platform data integration.

Main Methods:

  • Implementation of data structures and conventions to abstract platform-specific differences (hardware, OS, imaging software, UI).
  • Adoption of an object-oriented programming approach to enhance system modularity and portability.

Main Results:

  • Successful transfer of the DHCP Integrated Imaging System to X Window and Microsoft Windows workstations.
  • Demonstrated ability to integrate and display patient text, image, and graphics data across different platforms.

Conclusions:

  • The object-oriented approach significantly improved the portability of the DHCP Integrated Imaging System.
  • Effective use of data abstraction techniques facilitated the management of cross-platform complexities.
