# 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](./dicom-json.md) 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](dicom-web.md)), 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.
|
||
|
|
|
||
|
|
```json
|
||
|
|
{
|
||
|
|
"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.
