Data set for sub-millimetre MRI tissue class segmentation

Sub-millimetre 7Tesla MRI image data set of the human brain for supervised training of algorithms to perform tissue class segmentation. The dataset contains preprocessed MRI images (co-registered + bias corrected) and corresponding ground truth labels. The dataset contains two different acquisitions: - MPRAGE dataset, based on 5 subjects, with T1w, PDw and T2w images - MP2RAGE dataset, based on 4 subjects, with inv1, inv2 and me gre images The following ground truth labels are provided: [1] white matter [2] grey matter [3] cerebrospinal fluid [4] ventricles [5] subcortical [6] vessels [7] sagittal sinus Images are saved as nifti files and organized in BIDS format. This dataset is an extension of the following, initial dataset publication: * Dataset: A scalable method to improve gray matter segmentation at ultra high field MRI. The initial dataset is also available as a zenodo repository and can be downloaded from: https://zenodo.org/record/1206163
