Same instance number

hi everyone “Hi everyone, for one Series Instance UID, I am getting two SOP Instance UIDs with the same Instance Number (1). Why is this happening?”

Hi @Akash123

Orthanc does not control what gets into the Dicom tags. You can perfectly forge files with the same Instance Number, and you should indeed try to understand why they’re created like that in the first place. Is your modality correctly configured? Are you certain they’re in the same series, originally ?
