Muon-tomography is a rapidly evolving technique whis is widely and increasingly used in geology, geotechnics, and archaeology.The method provides an approximate 3D density distribution of the object under investigation (scanned), which is inherently loaded with artifacts. The analysis of the artifacts is essential for the interpretation and post-processing of the tomographic image, allowing the highlighting of the real density anomaly regions. In the poster presentation, the structure and characteristics of the artifacts will be analysed, depending on whether the source of the artifact is a real anomaly, measurement noise, side effect or perhaps an insufficiently accurate consideration of the topography. The anomaly contrast distortion effect of muographic mapping is also analysed. The results are illustrated with simulated and real measurement anomalies. The poster presentation will also cover the possibility of suppressing artifacts. The applicable procedures depend on the method of parameter discretization (voxelization) and the angular resolution of the muographic measurements recorded in different positions, but the applied regularization of the inversion procedure is the key factor in our study. In the presentation, results of parameter studies on these issues will be presented.
