We have written, optimized and tested a C/C++ project designed to simulate a CBCT experiment with an arbitrary shaped and structured three dimensional radiological phantom with high resolution and precision. This phantom was generated and later used to simulate the recording of the multiple cone beam projections under successive rotations of the coupled source and detector around it. This radiological phantom can be used to generate projections in the various testing chambers conditions and configurations including the mammography case. The synthesized projections were used to reconstruct the internal structure of the phantom with FDK algorithm. Our simulation code is also able to accept an arbitrary set of projections from other simulation software or from the real computer tomography setup. The simulation code includes various filtering techniques and has been hardware accelerated using the OpenMP directives.
