Abstract

A computer code was developed to simulate an X-ray imaging system, which is composed in X-ray source, object and detection parts. The physical principles are the X-ray attenuation law and the detecting probability based on deterministic methods. In the part of an X-ray source, it uses a source spectrum and prepares corresponding attenuation coefficients for object materials. A computer-aided drawing (CAD)-formatted file is used as the object geometry to make it convenient to describe complex 3-D object components. The number of pixel and the size of detector are variable in the part of a detector. Transmission images can be simulated with various X-ray energies, including spectrum and various system geometries. The simulation code has its graphic user interface (GUI), which makes it easy to perform selection of simulation parameters.
