In this study, we present the Chenonceau dataset : a novel 11.7T MRI dataset of the entire human brain, combining an ultra-high resolution anatomical scan at 100μm with diffusion scans at 200μm using strong diffusion sensitizations. To obtain this dataset, a unique acquisition protocol has been established : a fixed ex vivo brain has been cut into blocks compatible in size with a Bruker 11.7T MRI system. The blocks were scanned individually over an extended period of time. The collection of datasets was then registered back to a reference blockface acquired at 3T, thus resulting in a unique high resolution brain dataset.
