A new declarative design simplifies programs for the Digital Imaging and Communications in Medicine (DICOM) protocol. This approach makes DICOM implementations smaller, more extensible, and easier to validate.

Area of Science:

  • Medical Imaging Informatics
  • Health IT Standards
  • Radiation Oncology Systems

Background:

  • The Digital Imaging and Communications in Medicine (DICOM) protocol is a global standard for medical image exchange.
  • Implementing DICOM functionalities in software can be complex and lead to large, difficult-to-maintain codebases.
  • Existing radiation treatment planning systems often require custom interfaces for data transfer.

Purpose of the Study:

  • To present a novel declarative design for implementing the DICOM protocol.
  • To develop a more efficient and extensible approach for DICOM message handling.
  • To improve data transfer capabilities in radiation treatment planning systems.

Main Methods:

  • Developed a declarative programming model representing DICOM messages and sequencing.

  • Implemented an interpreter for this declarative DICOM language.
  • Integrated the design into a DICOM image storage server and a radiation treatment plan transfer facility for the Prism system.

    • Main Results:

    • Programs are significantly smaller, simpler, and more extensible compared to traditional procedural implementations.
    • Declarative expressions closely mirror DICOM specifications, enhancing clarity and maintainability.
    • The approach facilitates validation of DICOM specification consistency and implementation correctness.

    Conclusions:

    • The declarative design offers a robust and efficient method for implementing the DICOM protocol.
    • This approach enhances software development for medical imaging and radiation oncology applications.
    • The methodology is generalizable to other complex protocols and can aid in new protocol design.
