Welcome to the website of the PROcessing & VIsualization in Diffusion Imaging (PROVIDI) Lab, which is part of the Image Sciences Institute University Medical Center Utrecht, The Netherlands. The PROVIDI Lab, headed by Alexander Leemans, focuses on processing, analyzing, and visualizing diffusion MRI data for investigating microstructural and architectural characteristics of tissue organization.


Next ExploreDTI workshop: 4-6 December 2024 in Frankfurt, Germany!
