Simultaneous three-dimensional vascular and tubular imaging of whole mouse kidneys with X-ray µCT

µCT dataset of a mouse kidney injected with contrast agent XlinCA and scanned with 3.3 µm voxel size. Detailed sample preparation and image acquisition protocols are published as "Simultaneous three-dimensional vascular and tubular imaging of whole mouse kidneys with X-ray µCT" in Microscopy and Microanalysis. Segmentations of the vascular and tubular lumina along with the renal tissue are provided as masks. The three different segmented features were combined into a single dataset and encoded as different gray values: 0: Background 51: Tubules 204: Tissue 255: Blood vessels The Supplemental Video features a computer graphics visualization of the segmented masks. Blood vessel lumina are rendered in red, tissue in transparent blue and tubular lumina in yellow.

本数据集为注射了造影剂XlinCA的小鼠肾脏的X射线显微计算机断层扫描（µCT）数据集，扫描体素尺寸为3.3 µm。详细的样品制备流程与图像采集方案已发表于"Microscopy and Microanalysis"期刊的论文"Simultaneous three-dimensional vascular and tubular imaging of whole mouse kidneys with X-ray µCT"（《基于X射线µCT的完整小鼠肾脏血管与肾小管三维同步成像》）。数据集附带血管腔、肾小管腔及肾脏组织的图像分割掩码（mask）。三种不同的分割目标被整合为单数据集，并以不同灰度值编码：0代表背景，51代表肾小管，204代表肾脏组织，255代表血管。补充视频展示了分割掩码的计算机图形可视化结果，其中血管腔以红色渲染，肾脏组织以半透明蓝色渲染，肾小管腔以黄色渲染。
