Artefacts in X-Ray Tomography
This Lorentz Center Workshop aims to initiate an in-depth discussion on the various artefacts that arise in X-ray tomography. The mismatch between the models based on theoretical X-ray physics and the real-world experiments plays a crucial role in making advanced algorithms work well on complex measurement data.
Distortions between physical reality on one hand and the available mathematical models on the other hand, arise from a variety of sources, including optical distortions and mechanical distortions. Together with image perturbations related to the mathematical inverse problems that are solved after acquiring the data, all of these aspects lead to so-called “artefacts”: structured distortions of the images that hamper image contrast and resolution.
This Lorentz Workshop aims to start an in-depth discussion on the various artefacts that arise in X-ray tomography and to catalogue these distortions. Moreover, we aim to propose both engineering-based and computation-based solutions for their reduction and involve new communities in the discussion.
