Hi,

We've been asked to anonymize images for an research project and only keep the age of the patient at time of aquisition (in years) and sex of the patient.

Unfortunatly the PateintAge tag (0010, 1010) was not populated on the aquisition modality.

Is there a way to calculate the age of the patient based on Patient Birthdate (0010,0030) and Study date (0008,0020)?

I've tried something with @dateinterval but I couldn't get it to work.

Any ideas how to solve this?

Grtz,

Nico

Not sure how to do that in CTP without some custom java coding, but I've done this before using dcmtk (dcmodify and dcmdump) and a simple bash script. See attached script. This script will fix the PatientAge tag recursively in the specified folder (in-situ without backup).

Kind regards,

Paul Groot
