Accelerated Deterministic Simulation of X-ray Attenuation Using Graphics Hardware

The CMOS detector is mounted such that the same sample can be measured with both HRPD (high- resolution X-ray powder diffraction) and CMOS detection systems without moving it..

The images have been computed on GPUs using full floating point precision (128 bits per pixel) or half floating point precision (64 bits per pixel). Three GPUs from NVIDIA have

The simulations were however restricted to monochromatic X-ray beams (i.e. inci- dent photons have the same energy) and finite point sourcesc. We have now extended the

The main contribution of this new paper is to demonstrate the usefulness of the library through its use in various medical applications where speed and accuracy are both

Similarly to real X- ray machines, a cross is projected on the the patient’ skin using a visible light source to represent the X-ray beam (see dark crosses on the anatomical models

In our application the source is a scenegraph containing multiple 3D triangular models, and the target corresponds to an X-ray radiograph or a sinogram. Every 3D model can be
