Automated MRI quality control

Every scan checked for artefacts on arrival.

Grid of sagittal brain MRI slices, each showing one artefact type
Artefacts the system flags: Gibbs ringing, folding, motion and ghosting, blurring, banding, bias field, zipper, noise and wrong labels.

A scan spoiled by motion or ghosting can cost a trial a time point if the problem is found late. QSA checks each scan as it arrives and sends problems back to the site early.

The classifiers are trained on artefacts simulated with physics-based generators, so they do not depend on large collections of rare corrupted scans (Ravì et al., Medical Image Analysis 2024).
