How to delete all studies in Orthanc at once

[Saiteja Jayanthi]

Hi All,
I am working with an Orthanc server with more than 100 studies, is there anyway to cleanup all the studies at once?

Looking for a solution to easily cleanup full Orthanc at once as it is painful to delete each and every study individually.

Can someone please help me on this?

Thanks,
Saiteja.

There is a simple way to empty the database.  In the configuration file orthanc.json change one of the following:

I do this for my windows install:

  // Maximum size of the storage in MB (a value of "0" indicates no

  // limit on the storage size)

  "MaximumStorageSize" : 0,   ( changer the 0 to 1, stop and restart the service, the will empty the data base to 1 MB.  give it some time to empty then change it back to 0 stop and restart the service again)

  // Maximum number of patients that can be stored at a given time

  // in the storage (a value of "0" indicates no limit on the number

  // of patients)

  "MaximumPatientCount" : 0,   ( changer the 0 to 1, stop and restart the service, the will empty the data base to 1 patient.  Give it some time to empty then change it back to 0 stop and restart the service again.  Now you only have 1 patient to delete.)

Best,

Terry

You can make a GET request to the /studies/ endpoint of the API to get a list of studies you want to delete.

Then you can iterate that list somehow, doing each time a DELETE request to the /studies/{id} endpoint.

Take a look here: https://book.orthanc-server.com/users/rest-cheatsheet.html

OrthancToolsJS includes a deletion list management and delete even a long list of ressources (patient/study/series) through the GUI
