dicomweb-proxy

A proxy to translate between DICOMWEB and traditional DICOM DIMSE services

Description

• A nodejs tool to easily connect a DICOMWEB capable DICOM viewer to one or more legacy PACS that only know DIMSE services.
• Comes preinstalled with the popular OHIF DICOM Web Viewer (version 3.10.1).
• Supports OHIF MPR (vtk.js) feature for viewing volumetric datasets
• multithreaded

What is it for?

• if you want to view image data from one or more legacy PACS that does not understand DICOMWEB nor come with a web-viewer

How does it work?

• the app should be installed within the hospital intranet and configured to connect via DIMSE networking to on or more PACS (peers)
• it hosts a default DICOMweb viewer (OHIF) which can be replaced
• the webserver exposes the default QIDO and WADOURI/WADORS API needed for the viewer and converts on the fly between the two protocols
• optionally: you can connect to a DICOMWEB-WEBSOCKET-BRIDGE and expose the data to the public (handle with care!)

Prerequisite

• nodejs 12 or newer

Setup Instructions - npm

• install in empty directory:
  npm init -y
npm install dicomweb-proxy

• update config file located in:
  ./node_modules/dicomweb-proxy/config

• or better: create config override, see: config

• start proxy:
  npx dicomweb-proxy

Setup Instructions - source

• clone repository and install dependencies:
  npm install

• update config file located in:
  ./config

• start proxy:
  npm start

What to modify

• (optional) change our port or AET

config.source = {
  aet: "SOURCE_AET",
  ip: "SOURCE_IP",
  port: "SOURCE_PORT"
};

• change peer(s) to your PACS

config.peers = [{
  aet: "TARGET_AET",
  ip: "TARGET_IP",
  port: "TARGET_PORT"
}, { more peers here...}];

• in case your PACS does not support C-GET, switch to C-Move:
  config.useCget = false;

• update webserver port:
  config.httpPort = 5000;

• open webbrowser and start viewing:
  e.g. http://localhost:5000
