The Iseult project started in 2001, with one fundamental idea in mind being to design and build a human brain “explorer” consisting of a whole-body magnet of 11.7T field. After nearly 20 years of research and development, integration and tests, first images were acquired in vitro with this unique MRI scanner in 2021. Approval from the regulatory agency was then obtained in 2023 to scan a first...

The human tongue is a muscular hydrostat whose intricate, three-dimensional muscle activity drives nearly every aspect of articulate speech. In this talk, I present an integrated computational framework for studying tongue biomechanics during speech using tagged and diffusion MRI. First, I introduce a sparse non-negative matrix factorization approach that decomposes voxel-level motion into...

The tongue's complex interdigitating muscle architecture makes it one of the most challenging organs to image. Understanding its structure and dynamics is critical for assessing functional outcomes in tongue cancer patients, who frequently suffer long-term impairments in speech and swallowing after surgery. We first demonstrated that diffusion-weighted MRI with constrained spherical...

Real-time MRI has transformed the study of speech production by allowing direct visualization of vocal tract movements during running speech. Beyond typical speech, its application to clinical populations has also been increasing. Stuttering offers a tempting test case: stuttering disfluencies have long been identified from auditory-perceptual records, and yet the underlying articulation has...

Very little work has been done on functional imaging of the cranial nerve nuclei in the brainstem in the context of motor control, including only one such study of phonation (Smith et al., 2025, doi:10.21437/Interspeech.2025-2444). That study presented preliminary results from 4 participants, using two candidate data collection protocols and demonstrating that differential brainstem activation...
