Is there any possible way to import DICOM images from file while retaining the original file creation date? I am currently trying to migrate images from a PikoPACS installation to Orthanc. The problem is that this effectively re-creates the files and changes the file creation date to the day they were imported. My client is using PostureRay, which unfortunately uses the file creation date as the “X-ray creation date” when searching, which they are dependent on to look up particular X-rays.
If you recreate a file, any operating system will assign a new file creation date. This is evidently not specific to Orthanc.
In your workflow, you should use the “Study Date” (0008,0020) DICOM tag.
