TWIX Anonymizer VB17

Windows software for anonymizing Siemens raw MRI data.

We are sharing a Windows tool for anonymizing TWIX raw data files (.dat) from Siemens MRI scanners that run software versions VB17 and VB18.

Anonymization is mandatory before raw data from patient exams can be shared with researchers. TWIX Anonymizer will eliminate patient information, including name, date of birth, and patient ID, while retaining institutional information, such as the site name, MRI machine data, and scan date.

How to Use

TWIX Anonymizer displays a window where the user can select a directory. Pressing the Start button initiates data anonymization, and the deidentified files appear with the suffix “_anonymized.”


TWIX Anonymizer 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).
