论文摘要
这是用碘化钾对比剂扩散的凝胶幻像的动态X射线断层扫描测量的文档。仅在http://www.fips.fi/dataset.php和Zenodo（doi：10.5281/Zenodo.7876521）上提供测量数据和其他材料，只要在Arxiv的数据和此文档中，科学界都可以开放使用科学界。 文件包含：（1）在两个不同的分辨率（binning级别）中组织成正弦图的凝胶幻像的连续测量值，以及一些可用于创建无基质的前向操作员和过滤后的反向预测重构的额外元数据； （2）使用更多投影的第一个测量，以及使用非常密集的角度采样的第18个时间步骤的额外测量，例如用于参考重建； （3）简短的示例代码，以展示如何使用数据测试和验证重建算法。
This is the documentation for dynamic X-ray tomography measurements of a gel phantom diffused with potassium iodide contrast agent. The measured data and additional materials are available at http://www.fips.fi/dataset.php and Zenodo (DOI:10.5281/zenodo.7876521) for open use by the scientific community, as long as the data and this documentation at arXiv are appropriately referenced. The files contain: (1) 17 consecutive measurements of the gel phantom organized into sinograms at two different resolutions (binning levels) and some additional metadata which can be used to create matrix-free forward operators and filtered back-projection reconstructions; (2) the first measurement using a greater number of projections, and an additional measurement of an 18th time step using very dense angular sampling, for example to be used for reference reconstructions; (3) short example codes to showcase how the data could be used to test and validate reconstruction algorithms.
