I am trying to set up an Orthanc (windows) server with Windows and MacOS clients. I have set up both and I can successfully transfer PACS images from a DVD into Orthanc using the basic SendSCU program. I see the studies in the OrthanC database from the OrthanC HTML page. When I attempt to query the OrthanC database from Horos, there are no patients showing up from the query. I tried putting in a patient name, and also tried a query with no name. There are other patients in Horos which I can send to OrthanC but I don't know if that proves anything since I can send studies other then I did set up the node in Horos successfully enough to perform a send.
My next thought was to see if I could set up OrthanC to "send" studies to Horos. This is not the way I wanted to do it but I wasn't able to find out where to define the node in OrthanC
In the OrthanC documentation I do see references to a configuration.json but cannot locate that file. I suspect the documentation is either out of date or for linux. I do see a set of configuration files called dicomweb.json, orthanc.json, postgresql.json, serve-folders.json, webviewer.json, and worklists.json in the configuration directory. I don't see a specific place to define the node I wish to query from nor am I sure that it would be the root of my problem.
I have a limited understanding of PACS but was able to set up an Osirix Proof of concept, with Windows clients. I just ran into a roadblock with some sort of network timeout and Osirix support was less than helpful so I decided to use Horos instead (for now).
Any help would be appreciated

Dear April,
I am trying to set up an Orthanc (windows) server with Windows and MacOS clients. I have set up both and I can successfully transfer PACS images from a DVD into Orthanc using the basic SendSCU program. I see the studies in the OrthanC database from the OrthanC HTML page. When I attempt to query the OrthanC database from Horos, there are no patients showing up from the query. I tried putting in a patient name, and also tried a query with no name. There are other patients in Horos which I can send to OrthanC but I don’t know if that proves anything since I can send studies other then I did set up the node in Horos successfully enough to perform a send.
To configure DICOM query/retrieve, Orthanc must be configured so as it knows the DICOM parameters of the Horos modality. In other words, you’ll need to add the Horos modality to the “DicomModalities” configuration option of Orthanc.
The topic of DICOM networking is covered in the Orthanc Book, please make sure to carefully read and understand it:
http://book.orthanc-server.com/faq/query-retrieve.html
http://book.orthanc-server.com/dicom-guide.html#dicom-network-protocol
In the OrthanC documentation I do see references to a configuration.json but cannot locate that file.
The configuration of Orthanc is explained here:
http://book.orthanc-server.com/users/configuration.html
The location of the configuration depends upon your OS. If using GNU/Linux packages, it should be stored in the directory “/etc/orthanc/”. If using Microsoft Windows, you have a Start menu item that allows you to open the configuration file.
I suspect the documentation is either out of date or for linux. I do see a set of configuration files called dicomweb.json, orthanc.json, postgresql.json, serve-folders.json, webviewer.json, and worklists.json in the configuration directory.
This is “orthanc.json”. The other files contain the configuration of the plugins:
