Defacing Brain Scans.
With improvements in facial recognition softwares and high scan quality, there is an increased risk of participants being identified, as 2D MR scans can be reconstructed in 3D space. They are a threat to individual patient privacy, even when all other personal information has been removed.
Therefore, we use algorithms, to deface the scans like pydeface.
- Enable
pydefacein the Project Settings. - Then go to the
Processing Dashboardin theActionsMenu. - Click on
MR Sessions. - Select the subjects on which you want to run this process. Choose pydeface and launch the process.
-
Wait for the process to be completed.
- After removing the facial features the scan will look like this:
- Now, If we look at 3D reconstruction of say T2 weighted scan, it gets defaced like this:
