SUMMARY:Image quality transfer and democratization of MRI
DESCRIPTION:My talk will focus on Image Quality Transfer (Alexander et al Neuroimage 2017; Tanno et al Neuroimage 2021; Lin et al ISMRM 2021)\, and its role in international efforts to democratize MRI expertise and capability\, such as the CAMERA network https://www.medrxiv.org/content/10.1101/2022.05.02.22274588\nv1.full. The technique aims to use machine learning to estimate high quality images\, e.g. from a powerful experimental scanner\, from lower quality images\, e.g. acquired on a standard hospital scanner or low-field systems. I will talk through the history of development of these ideas\, show some of the latest results\, speculate about future opportunities\, and describe some challenges and observations of implementing these ideas in LMIC scenarios. I will also cover briefly some other aspects of my work at UCL on microstructure imaging\, e.g. NODDI (Zhang et al Neuroimage 2012) for neuroimaging and VERDICT (Panagiotaki et al Cancer Research 2013) for cancer imaging\, as well as disease progression modelling using techniques such as the subtype and stage algorithm (Young et al Nature Comms 2018) for mapping subtypes of chronic disease such as Alzheimer’s disease. \nBiography of the speaker: \nProfessor Alexander is the Director of the UCL Centre for Medical Image Computing (CMIC) at University College London (UCL) and Professor of Imaging Science in UCL’s Department of Computer Science.  His expertise is in computational modelling\, machine learning\, imaging and image analysis. He has a BA in Mathematics from the University of Oxford (1993)\, an MSc in Computer Science from UCL (1994)\, and a PhD in Computer Science from UCL (1998). He worked as a post-doc at the University of Pennsylvania until 2000 when he returned to London to take up an academic position. He became full professor in 2009\, Director of CMIC in 2015\, senior fellow of the ISMRM in 2017\, and fellow of the Royal Academy of Engineering in 2022 and IEEE in 2023.\n\nAll are welcome.
