收藏资源简介:
CTSpinoPelvic1K是一个融合了脊柱和骨盆的3D CT分割数据集,由三个公共数据源的病人级别交叉数据构建而成。数据集包含约650名患者的融合案例,其余患者的脊柱和骨盆标签分别针对不同的俯卧/仰卧采集。数据集提供了10类标签,包括背景、腰椎L1-L5、L6/LSTV、骶骨和左右髋骨。所有数据都规范化为PIR(后-下-右)方向,并且CT及其标签图共享相同的4×4仿射变换。此外,数据集还提供了关于腰椎骶化(LSTV)的注释,包括来自脊柱和骨盆的两个互补注释。数据集按70/15/15的比例分为训练、验证和测试集,并根据LSTV类别和匹配类型进行分层。数据以.npz文件格式存储,包含CT图像、标签、仿射矩阵和元数据。
CTSpinoPelvic1K is a fused spine + pelvis 3D CT segmentation dataset built by patient-level crosswalk between three public sources. The dataset includes approximately 650 patients with fused cases, while the rest have spine and pelvic labels targeting different prone/supine acquisitions. It provides 10-class labels, including background, lumbar vertebrae L1-L5, L6/LSTV, sacrum, and left/right hips. All volumes are canonicalized to PIR (Posterior-Inferior-Right) orientation, and the CT and its label map share the same 4×4 affine transform. Additionally, the dataset includes annotations for lumbosacral transitional vertebrae (LSTV), with two complementary annotations from spine and pelvic sources. The dataset is split into 70/15/15 for training, validation, and testing, stratified by LSTV class and match type. Data is stored in .npz files containing CT images, labels, affine matrices, and metadata.
