gVirtualXRay is a C++ library to simulate X-ray imaging. It is based on the Beer-Lambert law to compute the absorption of light (i.e. photons) by 3D objects (here polygon meshes). It is implemented on the graphics processing unit (GPU) using the OpenGL Shading Language (GLSL). SimpleGVXR is a smaller library build on the top of gVirtualXRay. It provides wrappers to Python, R, Ruby, Tcl, C#, Java, and GNU Octave.

MCX is a GPU-accelerated, general-purpose, physically-accurate and feature-rich 3-D light transport simulator. It is one of the fastest simulators because it can use tens of thousands of GPU threads to simulate photons in parallel.

DIANNA (Diffraction Analysis of Nanopowders) is a free software developed to simulate atomic models of structures from an ensemble of nanoparticles and to calculate their whole X-ray powder diffraction patterns and the radial distribution function. The main objects of investigation are the particles whose coherent scattering domains do not exceed several nm. DIANNA is based on the ab initio method using the Debye scattering equation. This method makes it possible to obtain information on the atomic structure, shape and size of nanoparticles. ...

SIMulation to EXPeriment is software that allows the direct comparison of simulation density information with that obtained from X-ray and neutron scattering experiments, by converting the simulation data to form factors. It also calculates volume probability distributions according to a space filling volumetric model. Written in C++ and Qt, SIMtoEXP has a very simple and easy to use GUI with interactive plotting. The software was originally developed by Norbert Kucerka. ...

Ray Watch is a cross-platform Ray Tracer written entirely in C++. Currently, the project supports basic primitives and all the finer stuff like reflection, refraction, specularity and soft shadows.

Open-source CT/ Radiography simulation package. XRaySim works seamlessly with commercial CAD packages and performs highly detailed scan simulations, with virtual X-ray sources and detectors, simulating cracks/ inclusions etc. very easily

A family of programs for building coarse-grained models (eg. of macromolecules), manipulating them (geometrical transformations and more) and calculating their X-ray scattering patterns (1D and 2D too). Uses PVM for parallelization.

Virtuelium is an open-source multi-spectral physically based ray-tracer developed to render the visual appearance of material and to be able to do multi-scaled simulations of light interactions.

bwfirt (Benchmark Without Fast Interactive Ray Tracing) is a framework for benchmarking ray tracing kernels in the context of a realistic light simulation application.

SpectrumGUI can generate filtered spectra for various x-ray tubes and can display attenuation coefficients for various materials. It also computes exposure and beam quality for various tube settings.
