Tomographic X-Ray Data Of Carved Cheese

This is an open-access dataset of tomographic X-ray data of a carved cheese. The dataset consists of

the X-ray sinogram of a single 2D slice of the cheese slice with three different resolutions, and
the corresponding measurement matrices modeling the linear operation of the X-ray transform.

Each of the sinograms was obtained from a measured 360-projection fan-beam sinogram by down-sampling and taking logarithms. The original (measured) sinogram is also provided in its original form and resolution.

Documentation of the dataset is available at arxiv.org/abs/1705.05732. See also www.fips.fi/dataset.php.

本数据集为开放获取的雕刻奶酪X射线断层扫描数据集合。该数据集包含两部分：一是单张奶酪二维切片的三种不同分辨率的X射线正弦图（sinogram），二是用于建模X射线变换线性运算的对应测量矩阵。
所有正弦图均由实测的360投影扇束正弦图通过下采样与对数变换得到。原始（实测）正弦图也将以其原始格式与分辨率一并提供。
