It has been used with great success for studying gas\u2013liquid as well as gas\u2013solid flows. Here, we apply this technique to analyze density-driven particle segregation in a rotating drum as an exemplary use case for analyzing industrial particle mixing systems. As glass particles are used as the denser of two granular species to be mixed, beam hardening artefacts occur and hamper the data analysis. In the general case of a distribution of arbitrary materials, the inverse problem of image reconstruction with energy-dependent attenuation is often ill-posed. Consequently, commonly known beam hardening correction algorithms are often quite complex. In our case, however, the number of materials is limited. We therefore propose a correction algorithm simplified by taking advantage of the known material properties, and demonstrate its ability to improve image quality and subsequent analyses significantly.<\/jats:p>","DOI":"10.3390\/s24102964","type":"journal-article","created":{"date-parts":[[2024,5,7]],"date-time":"2024-05-07T11:00:10Z","timestamp":1715079610000},"page":"2964","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Simplified Beam Hardening Correction for Ultrafast X-ray CT Imaging of Binary Granular Mixtures"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2195-6012","authenticated-orcid":false,"given":"Martina","family":"Bieberle","sequence":"first","affiliation":[{"name":"Helmholtz-Zentrum Dresden-Rossendorf, Institute of Fluid Dynamics, Bautzner Landstr. 400, 01328 Dresden, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4010-4408","authenticated-orcid":false,"given":"Theodoros Nestor","family":"Papapetrou","sequence":"additional","affiliation":[{"name":"Helmholtz-Zentrum Dresden-Rossendorf, Institute of Fluid Dynamics, Bautzner Landstr. 400, 01328 Dresden, Germany"},{"name":"Institute of Power Engineering, TUD Dresden University of Technology, N\u00f6thnitzer Str. 69, 01062 Dresden, Germany"}]},{"given":"Gregory","family":"Lecrivain","sequence":"additional","affiliation":[{"name":"Helmholtz-Zentrum Dresden-Rossendorf, Institute of Fluid Dynamics, Bautzner Landstr. 400, 01328 Dresden, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3558-5750","authenticated-orcid":false,"given":"Dominic","family":"Windisch","sequence":"additional","affiliation":[{"name":"Institute of Power Engineering, TUD Dresden University of Technology, N\u00f6thnitzer Str. 69, 01062 Dresden, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3428-5019","authenticated-orcid":false,"given":"Andr\u00e9","family":"Bieberle","sequence":"additional","affiliation":[{"name":"Helmholtz-Zentrum Dresden-Rossendorf, Institute of Fluid Dynamics, Bautzner Landstr. 400, 01328 Dresden, Germany"}]},{"given":"Michael","family":"Wagner","sequence":"additional","affiliation":[{"name":"Institute of Power Engineering, TUD Dresden University of Technology, N\u00f6thnitzer Str. 69, 01062 Dresden, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7371-0148","authenticated-orcid":false,"given":"Uwe","family":"Hampel","sequence":"additional","affiliation":[{"name":"Helmholtz-Zentrum Dresden-Rossendorf, Institute of Fluid Dynamics, Bautzner Landstr. 400, 01328 Dresden, Germany"},{"name":"Institute of Power Engineering, TUD Dresden University of Technology, N\u00f6thnitzer Str. 69, 01062 Dresden, Germany"}]}],"member":"1968","published-online":{"date-parts":[[2024,5,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"230","DOI":"10.1016\/j.advms.2017.12.002","article-title":"Low-Dose Computed Tomography Screening Reduces Lung Cancer Mortality","volume":"63","author":"Ostrowski","year":"2018","journal-title":"Adv.
