收藏资源简介:
TotalSegmentator MRI v2.0.0数据集是一个公开的医学影像数据集,包含616个异质性MRI扫描(T1、T2、PD、DIXON-style等序列,多种场强、扫描仪、切片厚度、对比剂),并带有50个解剖结构的体素级注释,覆盖全身。数据集分为561个训练样本和55个内部测试样本。数据集的注释流程包括初始分割、手动分割、模型预测和手动修正,所有注释均由经验丰富的放射科医生审核。数据集的结构包括每个扫描的MRI图像和对应的50个二进制掩码文件。数据集的总大小约为5.8 GB,采用CC BY-NC-SA 2.0许可证(非商业用途)。
The TotalSegmentator MRI v2.0.0 dataset is a public release of 616 heterogeneous MRI scans (T1, T2, PD, DIXON-style and other sequences, multiple field strengths, scanners, slice thicknesses, contrast agents) with voxel-wise annotations of 50 anatomical structures spanning the whole body. The dataset is divided into 561 training samples and 55 internal test samples. The annotation pipeline includes initial segmentations, manual segmentation, model predictions, and manual refinements, with all annotations reviewed by a board-certified radiologist. The dataset structure includes MRI images and corresponding 50 binary mask files for each scan. The total size of the dataset is approximately 5.8 GB, licensed under CC BY-NC-SA 2.0 (non-commercial).
