I am trying to export dicom file (.dcm) after de-identification from dicom store to GCS bucket. Once the operation is successful, the image gets loaded in gcs bucket but the file name is in numerical format. Is there any way to export the file with original file name.

For example :
source dicom filename : source.dcm
exported dicom filename :1.3.6.1.4.1.11129.5.1.285203166265972638872377502038110961072/1.3.6.1.4.1.11129.5.1.12890303936119703509451462489773813927/1.3.6.1.4.1.11129.5.1.216682955412074535971523503539344066890.png

I want to destination filename same as source filename for easy identification and further analysis.

The export operation always stores the image in the folder: studyUID/seriesUID/instanceUID of the DICOM file that you are exporting. Only the contents of the DICOM file that is imported/stored in the Healthcare API is stored. The name of the file is not really a part of the dicom file ie it is not part of the contents and hence is not stored in the API.

  • what if I have 5 source images and after exporting I will be having 5 images with some different name. Then how can I map the pre and post images one to one? – code tutorial Apr 24 '20 at 16:15
  • If you have 5 images: img1: study1/series1/instance1 img2: study1/series1/instance2 img3: study1/series1/instance3 img4: study1/series1/instance4 img5: study1/series1/instance5 They will be stored in the new Dataset according to their UIDs - so you can map img1 to the new file: study1/series1/instance1 – Pooja Venkatram Apr 24 '20 at 17:18
  • /{study_id}/{series_id}/{instance_id} is auto-generated for every image. How can customize them according to my need. Requesting you to provide an example on this. – code tutorial Apr 24 '20 at 18:58
  • You can view the study_uid, series_uid and instance uid using tool like dcmdump (https://support.dcmtk.org/docs/dcmdump.html). Usage: dcmdump If you want to modify tags like UIDs you can use dcmodify(https://support.dcmtk.org/docs/dcmodify.html) For example: To modify StudyInstanceUID to study1: dcmodify -m "(0020,000D)=study_1" To modify SeriesInstanceUID to series1: dcmodify -m "(0020,000E)=series_1 To modify SOPInstanceUID to instance1: dcmodify -m "(0008,0018)=instance_1" Tags reference: https://www.dicomlibrary.com/dicom/dicom-tags/ – Pooja Venkatram Apr 24 '20 at 21:25
