# Serve Static DICOMweb files off Nginx HTTP/Web Server 

This is an example of how a Static DICOMweb dataset can be hosted on a Nginx server to be integrated with a DICOMweb-enabled viewer, such as [OHIF](https://ohif.org/).

## Notes
1. Thanks to [Bill Wallace](https://github.com/wayfarer3130) for helping with this 🙏
2. This may or may not be the best, most performant, etc. way to do to this. It is only intended as a reference.
3. This assumed you have your Static DICOMweb dataset placed at `/usr/share/nginx/html/dicomweb`
