Batch anonymization

Hi Marcel,

I hope you are doing well. At AVL I got a few requests to run anonymization in batch mode, i.e. for multiple patients at once.

To achieve this I looked at connecting the Conquest DICOM server to ZeroBrane Studio to open up the scripting capabilities. I came up with this solution:

1. Create a local file e.g. "anonpat.lua" with the following content:

b = DicomObject:new()
b.PatientID=123456 -- 1. Change This
b.StudyInstanceUID=''
a=dicomquery('CONQUESTSRV1', 'STUDY', b) -- 2. Change This


NewPatientID='xxxaaabbb' -- 3. Change This


for i=0,#a-1 do
  if a[i].StudyInstanceUID then
    print('Mapping.. ' .. a[i].PatientID .. ':' .. a[i].StudyInstanceUID)
    servercommand('modifystudy:' .. b.PatientID .. ',' .. a[i].StudyInstanceUID .. ',lua/anonymize_script.lua(' .. NewPatientID .. ')' )
  end
end

2. Modify the three lines of code marked with "Change This" to your liking. For large scale anonymization we can optimize this by e.g. reading the pair of new and old names from a text file. Note: the name 'CONQUESTSRV1' has to match with an entry in your ACRNEMA.MAP (4th screen of the Conquest DICOM server).

3. Start ZeroBrane Studio and connect it to your local DICOM server (this may require to run the install.lua script from the lua folder for the DICOM server first).

4. Run the script above by pressing the "Play" button twice

Is this also how you would suggest to do this, or is there a more straightforward approach?

Best regards,

Lennert.

Hi Marcel,

Thank you for your swift reply. My understanding was that the "'modifystudy" command required a valid StudyInstanceUID, but it seems that it can be left out. In windowsmanual.pdf it is documented as:

Quote

--modifystudy:p,s,script Change items in patient or study

Having a shortcut like "--anonymize:oldpatid,newpatid" would further facilitate this process. Does this sound reasonable?

Best regards,

Lennert.

Thanks again Marcel.

Currently anonymization is only performed on local DICOM servers, so I do not expect that anonymization will take more than 5 minutes this way. Fortunately, we have the technique of using the "modifystudy" command documented this way, so hopefully others can benefit from my hunt for a solution.

Best regards,

Lennert.
