Democratising White Matter Exploration with Ultra-Low Field MRI

Portable MRI scanners, while often low-cost, face challenges like low SNR, gradient and field non-uniformity, and heating-induced drift. By addressing these issues we’ve advanced white matter imaging from ADC maps to DTI, spherical deconvolution, and whole-brain tractography, & tentatively explored connectomics and quantitative myelin metrics for edge-weights. While such advances democratize neuroimaging & expand research to diverse populations, low system cost is crucial for true accessibility.
