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.

互联网脑分割存储库（Internet Brain Segmentation Repository, IBSR）提供人工引导的专家分割结果与磁共振脑成像数据，其设立宗旨为推动脑分割方法的评估与技术发展。本数据集包含1.5mm层厚的成像数据，目前共收录18名年龄介于7至71岁之间的受试者数据。每位受试者的数据包含：1）仅经旋转校正、已空间标准化至Talairach坐标系定向的T1加权容积成像（T1-weighted volumetric images）；需注意，上述数据已通过CMA的“自动分割（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。
