Internet Brain Segmentation Repository (IBSR) 1.5mm dataset

The Internet Brain Segmentation Repository (IBSR) provides manually-guided expert segmentation results along with magnetic resonance brain image data. Its purpose is to encourage the evaluation and development of segmentation methods. This data set includes 1.5mm data. Eighteen subjects aged 7-71 are currently available. For each subject there is: 1) T1-weighted volumetric images that have been 'positionally normalized' into the Talairach orientation (rotation only). Also note that these data have been processed by the CMA 'autoseg' biasfield correction routines; 2) Segmentation results for 'general segmentation' of 43 individually labeled principal gray and white matter structures of the brain.

互联网大脑分割存储库（Internet Brain Segmentation Repository, IBSR）提供经人工指导的专家分割结果与磁共振脑图像数据。其核心目标为推动分割方法的评估与开发工作。本数据集包含1.5mm分辨率的影像数据，目前共收录18名年龄介于7至71岁之间的受试者数据。每名受试者的数据包含以下两项内容：1）仅通过旋转操作完成空间归一化、适配塔莱拉什定向（Talairach）的T1加权容积图像；需特别说明，此类数据已通过CMA的“autoseg”偏场校正程序完成预处理；2）针对大脑43个单独标注的主要灰质与白质结构的通用分割结果。
