Other AbstractDeveloping X-ray observation facility has been planned in the Chinese space station. Simulating the process of three-dimensional X-ray imaging can offer valuable reference for the facility development. The simulation process can be divided into three steps. Firstly, to use the cone beam X-ray to scan an object, and rotate the object to obtain projection images at enough number of views; Secondly, to reconstruct the scanned object according to the projection images and the geometrical information; Finally, to visualize the reconstruction object. By employing a 3D Shepp-Logan model consisting of 10 interlapped ellipsoids with different linear attenuation coefficients as the object, the processes of projection, back projection and 3D visualization are realized by simulation, and through image reconstruction, the stereo structure of the scanned object can be well displayed.
