TWIX Anonymizer VB17

TWIX Anonymizer VB17

Kai Tobias Block

The TWIX Anonymizer is a small Windows tool for anonymizing TWIX raw data files (.dat) from Siemens MRI scanners running the software versions VB17 or VB18. This is a mandatory procedure before raw data from patient exams can be shared to researchers. The software will eliminate patient information including patient name, date of birth, and patient ID. Institutional information (site name, MRI machine, date of scan) will remain in the file.


The program shows a dialog where the user can select a directory. By pressing the Start button, it will anonymize all TWIX .dat files in that directory. Anonymized TWIX files then have the suffix "_anonymized" in the file name.

NOTE: This software only supports raw data files from the Siemens syngoMR versions VB17A and VB18P. Files from the VDxx software versions are not supported (in the VDxx software versions, data can be directly anonymized from the TWIX tool).
