this project performs forward projection calculations for cone-beam CT using Siddon's and Jacobs' algorithm respectively There are seven files in the folder. 'Ax': the entrance to the Jacobs' algorithm. 'Ax_siddon': the entrance to the Siddon's algorithm. 'Nf_M3D': the implementation of the Jacobs' algorithm. 'Nf_M3D_siddon': the implementation of the Siddon's algorithm. 'ParaSet': the system setting. 'phantom3dAniso': the generation of phantom data. 'test_proj': the entrance to the project.
