Static X-ray CT and PET imaging datasets on a fractured basalt core sample

The datasets contain three-dimensional tomographic images of a saw-cut fractured basalt core acquired using positron emission tomography (PET) and clinical X-ray Computed tomography (X-ray CT). For PET, the scans are taken at steady-state following the injection of an aqueous 18F-FDG and the dataset depicts the distribution of the injected radiotracer within the fractures and pore spaces of the basalt core. For X-ray CT, two sets of scans are provided, which include raw tomographic images of the fractured basalt core imaged when the sample is completely dry and when the sample is saturated with water. These datasets were used in Kurotori et al. (2022)* to assess quantitatively the applications of PET and X-ray CT for measuring micrometer-scale fracture aperture distributions in heterogeneous rocks. Further details on the datasets can be found in Kurotori et al. (2022) and the attached Readme file.本数据集包含利用正电子发射断层扫描（positron emission tomography，PET）与临床X射线计算机断层扫描（X-ray Computed Tomography，X-ray CT）获取的锯切裂隙玄武岩岩心三维断层扫描图像。针对PET扫描，其数据采集于注射水性18F-FDG后的稳态阶段，该数据集呈现了注入的放射性示踪剂在玄武岩岩心裂隙与孔隙空间内的分布情况。针对X射线CT，则提供了两组扫描数据，分别为样本完全干燥以及样本被水饱和状态下采集的裂隙玄武岩岩心原始断层扫描图像。上述数据集曾被应用于Kurotori等人（2022）的研究*中，用于定量评估PET与X射线CT在非均质岩石中测量微米级裂隙开度分布的应用效果。有关该数据集的更多详细信息，可参阅Kurotori等人（2022）的研究成果及附带的Readme文件。
