Summary

This study introduces a secure DICOM-Network Attached Server (DICOM-NAS) to connect hospital DICOM servers to the internet. The DICOM-NAS enhances medical image security by temporarily storing data, preventing unauthorized access to sensitive patient information.

Area of Science:

  • Medical Imaging
  • Network Security
  • Health Informatics

Context:

  • Connecting web-based servers to existing DICOM servers presents security challenges.
  • Internet use of web-based servers for medical imaging carries inherent risks.
  • Securely accessing hospital DICOM data remotely is crucial for modern healthcare.

Purpose:

  • To design and develop a secure DICOM-Network Attached Server (DICOM-NAS).
  • To enable secure internet connectivity for hospital Digital Imaging and Communications in Medicine (DICOM) servers.
  • To bridge the DICOM protocol and HTTP for efficient and secure image transfer.

Summary:

  • The DICOM-NAS acts as an intermediary, receiving client export requests and forwarding them to the hospital's DICOM server via the DICOM protocol.

  • Upon retrieval, the DICOM server sends images to the DICOM-NAS, which then transfers them to the client using HTTP.
  • The DICOM-NAS only temporarily stores requested images, with the original DICOM images remaining securely on the hospital's DICOM server, thus preventing unauthorized access.

    • Impact:

    • Significantly enhances information security for medical imaging data.
    • Mitigates risks associated with direct internet exposure of hospital DICOM servers.
    • Facilitates secure remote access to medical images with features like reporting and MPR, without requiring substantial storage on the intermediary server.
