The software aRTist is a simulation tool for creating realistic radiographs of virtual radiographic structures. With radiographic simulations, virtual component models can be scanned like in a computer tomograph. The aim of Virtual CT with aRTist is to provide a computer simulation which the current issues in X-ray computed tomography can be viewed.
aRTist expands the options for configuring tomographic scans for radiographic simulation. The focus is on the use of simulation to optimize computer tomography, to develop new scanning strategies and to determine the accuracy of dimensional measurements.
aRTist is a practical simulation tool for creating realistic radiographic images of virtual scenes from CAD objects. Virtual computed tomography offers new possibilities for the investigation of parameter influences. In addition to the possibility of switching physical effects on and off, e.g. scattered radiation, scanning movements can also be tested before they are technically implemented. aRTist is a practical simulation tool for creating realistic radiographic images of virtual scenes from CAD objects.
Virtual Computed Tomography
An expansion module automates the simulation of tomographic scans. Simply by specifying the desired number of projections, the current radiographic arrangement becomes a tomography simulation.
Unlike in reality, the primary radiation component and the scattered radiation component can be shown separately in the simulation. This makes it possible to investigate the formation of scattered radiation artifacts in computer tomography (gray value fluctuations in homogeneous material areas).
Test objects represented by STL geometries are modeled in a virtual radiographic setup with radiation source and detector. The physical models from radiation generation to detection enable quantitative simulation results. Analytical models for radiation propagation are combined with Monte Carlo models for taking into account scattered radiation.
Over 60 licensees od aRTist are stated to be in use in research and industry worldwide. Virtual computed tomography is currently being used and further developed in projects that are funded by the EU and the BMBF. EU: AdvanCT (EMPIR 17IND08) BMBF: CTSimU (WIPANO)
