Data anonymization in TPC
Patient privacy protection
Any un-authorized collection of patient or control subject records is strictly forbidden. Any data containing any possibility of patient or control subject identification must not be taken outside the premises of Turku University Hospital or Turku PET Centre.
Please note that medical images may contain information for patient identification.
Even regional tissue data and
blood or plasma data may sometimes contain patient identification
PET Centre provides software (
ecatanon) for removal of this
information, and researcher is responsible for doing this before image or raw data is copied outside
the hospital and/or given to any person who is not registered as an employee or researcher in
Turku PET Centre. This applies also to the data copied to personal laptops or USB devices that
may be taken outside of the hospital.
Anonymization of DICOM images
DICOM image data can be anonymized in the most recent Carimas version, or using separate program
dcmanon with graphical user-interface.
Alternatively, DICOM images can be anonymized with command-line program dcmanoncom:
For example, if DICOM folder is
S:\temp\dicom, then enter command
dcmanoncon "s:\temp\dicom" --out="s:\temp\anonym"
to get the anonymized copies into folder
If you would like to process also all subfolders, then add option
-R, for example:
dcmanoncon -R "s:\temp\dicom" --out="s:\temp\anonym"
Notice that this only removes the subject identification information inside DICOM images, but DICOM folder names may also contain the subject name or other information that needs to be removed manually.
For more information please contact Timo Laitinen.
Anonymization of ECAT images
In ECAT 6.3 and 7.x files this information can be removed using ecatanon version 4.3 or later. This program can be used in PC/Windows command shell in all computers connected to hospital network.
Please note that if this program is executed without any command-line options, it will by default
not delete the patient identification information.
-n +f -i -s are recommended, for example:
ecatanon -n +f -i -s *.v
Anonymization and format conversion
If image is converted to another format using
the data can be optionally anonymized during the process.
