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 3.8.0).

Note: Since OHIF 3 is still beta you can also switch back to OHIF 2 version: just remove the public directory and unzip public.zip to public

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.webserverPort = 5000;`

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