Simulation of cephalometric imaging. Simulation of conventional cephalometric imaging using digitally reconstructed radiographs (DRR) from 3D CBCT image data. The DRR of the bones were generated by casting rays from the X-ray source through the volume of the CT-derived bone models. Each of these rays went through a number of voxels of the volume, the attenuation coefficients of which were then integrated along the ray and projected onto the imaging plane to obtain a DRR image resembling a radiograph.
