Dear community,

I’m asking for your help because I need to understand what instances of the API to use if I want to:

- Create a study in the Orthanc server
- Upload the images related to the study in the Orthanc server

Thanks for your help.

Hi Juan,

You can’t create an empty study in Orthanc.  
You could use the `/tools/create-dicom` ( see [Orthanc REST API](https://api.orthanc-server.com/index.html#tag/System/paths/~1tools~1create-dicom/post) and [Convert png/JPEG to DICOM format - #9 by jodogne](https://discourse.orthanc-server.org/t/convert-png-jpeg-to-dicom-format/1534/9)) route to create the study with your first image and then add the other images to the newly created study.

HTH,
