Medical Image Alignment Assessment as a Test of Generalist Visual Reasoning in Frontier Multimodal Models
Ross Callaghan, Niannu Gao, Hojjat Azadbakht +1
Frontier multimodal large language models (MLLMs) are increasingly positioned as general purpose visual reasoners as part of the quest for artificial general intelligence. A key te…
Eddeep: a deep-learning framework for fast eddy-current distortion correction in diffusion MRI
Antoine Legouhy, Ross Callaghan, Yuchuan Qiao +4
Diffusion MRI (dMRI) relies on diffusion-weighted echo-planar imaging, which is highly susceptible to eddy-current-induced geometric distortions. These distortions vary across diff…
When Brains Disagree: Biological Ambiguity Underlies the Challenge of Amyloid PET Synthesis from Structural MRI
Louise E. G. Baron, Ross Callaghan, David M. Cash +3
Structural MRI-to-amyloid PET synthesis has been proposed as a non-invasive alternative for amyloid assessment in Alzheimer's disease (AD). However, reported performance of identic…
Polaffini: A feature-based approach for robust affine and polyaffine image registration
Antoine Legouhy, Cosimo Campo, Ross Callaghan +2
In this work we present Polaffini, a robust and versatile framework for anatomically grounded registration. Medical image registration is dominated by intensity-based registration…
