Neutron tomography of petrified wood

The data set contains the projections a piece of petrified wood produced during a neutron CT scan. The purpose of the data is to provide a training data set for users of the open source CT reconstruction software MuhRec https://github.com/neutronimaging/imagingsuite. The data was acquired in 2008 at the cold neutron imaging beamline ICON at Paul Scherrer Institute. The beamline has a collimation in the order of L/D=400 which provides an essentially parallel beam. The setup used an ANDOR DV434 camera with a Pentax 50mm f/1.2 lens and a 100um 6LiF/ZnS scintillator. The pixel size of the projections is 158um. The original data has been cropped (to reduce data size) and converted from the camera file format fits into tiff.本数据集包含一块石化木在中子CT扫描过程中生成的投影数据。本数据集的用途是为开源CT重建软件MuhRec（https://github.com/neutronimaging/imagingsuite）的使用者提供训练用数据集。该数据集于2008年在保罗·谢尔研究所（Paul Scherrer Institute）的冷中子成像束线ICON上采集。该束线的准直比约为L/D=400，可提供近似平行的中子束流。实验装置采用ANDOR DV434相机，搭配宾得（Pentax）50mm f/1.2镜头以及100μm 6LiF/ZnS闪烁体。投影数据的像素尺寸为158μm。原始数据已被裁剪以减小数据规模，并从相机原始文件格式转换为TIFF格式。
