DICOMweb Proxy

You can launch the OHIF Viewer with a url that returns a JSON file which contains a DICOMWeb configuration. The DICOMweb Proxy constructs a DICOMweb datasource and delegates subsequent requests for metadata and images to that.

Usage is similar to that of the DICOM JSON datasource and might look like

https://viewer.ohif.org/viewer/dicomwebproxy?url=https://ohif-dicom-json-example.s3.amazonaws.com/dicomweb.json

The url to the location of the JSON file is passed in the query after the dicomwebproxy string, which is https://ohif-dicom-json-example.s3.amazonaws.com/dicomweb.json (this json file does not exist at the moment of this writing).

DICOMweb JSON configuration sample

The json returned by the url in this example contains a dicomweb configuration (see DICOMweb), in a "servers" object, which is then used to construct a dynamic DICOMweb datasource to delegate requests to. Here is an example configuration that might be returned using the url parameter.

{
"servers": {
"dicomWeb": [
{
"name": "DCM4CHEE",
"wadoUriRoot": "https://server.dcmjs.org/dcm4chee-arc/aets/DCM4CHEE/wado",
"qidoRoot": "https://server.dcmjs.org/dcm4chee-arc/aets/DCM4CHEE/rs",
"wadoRoot": "https://server.dcmjs.org/dcm4chee-arc/aets/DCM4CHEE/rs",
"qidoSupportsIncludeField": true,
"supportsReject": true,
"imageRendering": "wadors",
"thumbnailRendering": "wadors",
"enableStudyLazyLoad": true,
"supportsFuzzyMatching": true,
"supportsWildcard": true
}
]
}
}

The DICOMweb Proxy expects the json returned by the url parameter it is invoked with to include a servers object which contains a "dicomWeb" configuration array as above. It will only consider the first array item in the dicomWeb configuration.
