该数据集是一个大规模、一键式下载的资源，包含了超过114,000个头颈部的磁共振成像（MRI）体积数据，涵盖多种成像方式。这使得它成为迄今为止可自由访问的最大三维脑部成像数据集。该数据集还包括了匿名化处理和解剖学遮罩，以及为每种成像方式提供的标准化元数据和一个图像质量评分。其规模达到114,000个三维脑部MRI体积，任务专注于三维医学成像中的自监督学习（SSL）。

This dataset is a large-scale, one-click downloadable resource containing over 114,000 head and neck magnetic resonance imaging (MRI) volumetric data across multiple imaging modalities, making it the largest freely accessible 3D brain imaging dataset to date. It also includes anonymized data, anatomical masks, standardized metadata for each imaging modality, and an image quality score. With 114,000 3D brain MRI volumes in total, this dataset is dedicated to self-supervised learning (SSL) tasks in 3D medical imaging.
