XCT dataset single metal object for reconstruction

XCT datasets of a motor frame main frame section made of aluminium acquired with a Nikon 450 with rotating target with the flatpanel, including projections and reconstruction. Detector width of 2000 pixels and 3120 projections. Detector width of 1000 pixels and 1560 projections. The number of projections are highly composite numbers which make these datasets particularly usefull for testing limited data reconstruction with for example the open source software the Core Imaging Library by CCPi.本数据集为采用搭载旋转靶和平板探测器的尼康450（Nikon 450）设备采集的铝制电机机座主体段X射线计算机断层扫描（X-ray Computed Tomography，简称XCT）数据集，包含投影数据与重建结果。 探测器宽度为2000像素，投影数为3120幅。 探测器宽度为1000像素，投影数为1560幅。 投影总数均为高度合成数，使得本数据集尤其适用于有限数据重建算法的测试，例如可借助CCPi开发的开源软件Core Imaging Library（CIL）开展相关测试。
