BrLP is designed to predict the evolution of diseases at the individual level on 3D brain MRIs.

An efficient semi-supervised quality control system trained using physics-based MRI-artefact generators and adversarial training

no code implementations7 Jun 2022 Daniele Ravi, Frederik Barkhof, Daniel C. Alexander, Lemuel Puglisi, Geoffrey JM Parker, Arman Eshaghi

To tackle this problem, we propose a framework with four main components: 1) artefact generators inspired by magnetic resonance physics to corrupt brain MRI scans and augment a training dataset, 2) abstract and engineered features to represent images compactly, 3) a feature selection process depending on the artefact class to improve classification, and 4) SVM classifiers to identify artefacts.
