A polychromatic X-ray radiograph simulator has been developed to assist the structured exploration of the parameter space of X-ray computed tomography for dimensional and surface metrology. The simulator is capable of simulating polychromatic X-ray spectra, at user defined binning sets to produce radiographic images. This approach differs from existing simulation software in the use of a sparse matrix multiplication approach, between a geometry matrix and a voxel description, of the object to create both the cone beam and the focal spot geometries. Future work will aim to use this framework for the incorporation of scatter approximations.

Abstract
A polychromatic X-ray radiograph simulator has been developed to assist the structured exploration of the parameter space of X-ray computed tomography for dimensional and surface metrology. The simulator is capable of simulating polychromatic X-ray spectra, at user defined binning sets to produce radiographic images. This approach differs from existing simulation software in the use of a sparse matrix multiplication approach, between a geometry matrix and a voxel description, of the object to create both the cone beam and the focal spot geometries. Future work will aim to use this framework for the incorporation of scatter approximations.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
