我们提出了一个在体人脑磁共振成像（MRI）数据集的100分辨率。它包括在7特斯拉下以250 μm的标称各向同性分辨率采集的单个年轻健康白人受试者的T1加权全脑解剖数据，并使用前瞻性运动校正进行记录。原始数据约为1.2 TB，在8小时的总扫描时间内获得。该数据集的分辨率远远超过任何先前发表的体内结构全脑数据集。它的潜在用途是建立一个在体MR脑图谱。当原始数据可用时，可以改进用于图像重建和图像恢复的方法。对于高磁场强度和高分辨率数据，预处理和分割程序可能会得到增强。此外，可以评估定量数据分析中潜在分辨率引起的变化，例如皮质厚度或体积测量，因为存储库中还包括同一受试者的各向同性分辨率为1和0.5 mm的高质量图像。
We present an ultrahigh resolution in vivo human brain magnetic resonance imaging (MRI) dataset. It consists of T 1-weighted whole brain anatomical data acquired at 7 Tesla with a nominal isotropic resolution of 250 μm of a single young healthy Caucasian subject and was recorded using prospective motion correction. The raw data amounts to approximately 1.2 TB and was acquired in eight hours total scan time. The resolution of this dataset is far beyond any previously published in vivo structural whole brain dataset. Its potential use is to build an in vivo MR brain atlas. Methods for image reconstruction and image restoration can be improved as the raw data is made available. Pre-processing and segmentation procedures can possibly be enhanced for high magnetic field strength and ultrahigh resolution data. Furthermore, potential resolution induced changes in quantitative data analysis can be assessed, eg, cortical thickness or volumetric measures, as high quality images with an isotropic resolution of 1 and 0.5 mm of the same subject are included in the repository as well.
