Anonymization options in Easy DICOM Viewer

Easy DICOM Viewer can be used to anonymize DICOM tag values in your DICOM files.  There are 3 options you can select:

Anonymize basic patient information

This option anonymizes the most basic DICOM tags, which are the following:

  • patient’s name (0010, 0010)
  • patient ID (0010, 0020)
  • patient birth date (0010, 0030)
  • patient’s age (0010, 1010)
  • patient’s sex (0010, 0040)
  • comment (0010, 4000)
  • institution name (0008, 0080)
  • institution address (0008, 0081)
  • institution department (0008, 1040)
  • Issuer of Patient ID (0010, 0021)
  • study description (0008, 1030)
  • series description (0008, 103E)
  • operator’s name (0008, 1070)
  • referring physician’s name (0008, 0090)
  • physician(s) of record (0008, 1048)

Anonymize top level tags using NEMA specification

This option anonymizes tags using the recommendations outlined in this link – http://dicom.nema.org/dicom/2013/output/chtml/part15/chapter_E.html#table_E.1-1.

Compared to the basic anonymization option above, this option anonymizes a lot more details.

Apply tags template

This option lets you apply a tags template to the selected images.  A tags template is a set of changes you want to apply to the DICOM tags.  You can create multiple templates for different purposes e.g. one template to modify certain tags to a specific value, another template to erase only patient details, and yet another tag to modify all patient, doctor and study details.

The Preview window will then show you how the tag values would appear in the modified images.

These 3 options give you complete flexibility as to how you want to anonymize the DICOM tags in your images.

Anonymizing and editing DICOM tags

You may sometimes want to modify the tag values in your DICOM images to maintain patient anonymity.  To do that in Easy DICOM Viewer, simply click on the Export series or images button

select the Anonymize top level tags option, and enter the value (ANONYMOUS by default) to replace the existing values.

The top level tags that are anonymized follows the recommendations outlined here (http://dicom.nema.org/dicom/2013/output/chtml/part15/chapter_E.html#table_E.1-1).

If you want more control over which tags are modified and with what values, you can use tag templates.  You can define one or more templates and use them whenever necessary.  The list of existing templates are listed in the drop down list when you select the Apply tags template option.

To create or edit templates, click on the Edit templates button.  In the Tag Templates window, you can define how the DICOM tags should be modified.  For more details, please see this link.

Among other actions, you can:

  • generate UUID-derived UID values for tags that require such values
  • reuse the same UID values for all images in the same series
  • use existing tag values as part of the new values
  • modify tags at all levels, not just at the top level
  • delete all private tags
  • delete all tags
  • view a preview of the values before and after applying your changes
