Applied MRI Research Group

​Applied MRI Research and Diagnostic Imaging 

We develop new techniques for MRI and other imaging modalities, and then deploy them in clinical applications in collaboration with specialist researchers. In parallel with this, we also seek evidence for the physiological sources of signals.We also undertake safety assessments and quality control for the techniques in accordance with international guidelines.
