Imaging"],"abstract":"<jats:p>Reproducibility is a cornerstone of scientific progress, yet in X-ray computed tomography (CT) reconstruction, it remains a critical and unresolved challenge. Current benchmarking practices in CT are hampered by the scarcity of openly available datasets, the incomplete or task-specific nature of existing resources, and the lack of transparent implementations of widely used methods and evaluation metrics. As a result, even the fundamental property of reproducibility is frequently violated, undermining objective comparison and slowing methodological progress. In this work, we analyze the systemic limitations of current CT benchmarking, drawing parallels with broader reproducibility issues across scientific domains. We propose an extended data model and formalized schemes for data preparation and quality assessment, designed to improve reproducibility and broaden the applicability of CT datasets across multiple tasks. Building on these schemes, we introduce checklists for dataset construction and quality assessment, offering a foundation for reliable and reproducible benchmarking pipelines. A key aspect of our recommendations is the integration of virtual CT (vCT), which provides highly realistic data and analytically computable phantoms, yet remains underutilized despite its potential to overcome many current barriers. Our work represents a first step toward a methodological framework for reproducible benchmarking in CT. This framework aims to enable transparent, rigorous, and comparable evaluation of reconstruction methods, ultimately supporting their reliable adoption in clinical and industrial applications.<\/jats:p>","DOI":"10.3390\/jimaging11100344","type":"journal-article","created":{"date-parts":[[2025,10,2]],"date-time":"2025-10-02T15:07:48Z","timestamp":1759417668000},"page":"344","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["No Reproducibility, No Progress: Rethinking CT Benchmarking"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1055-3464","authenticated-orcid":false,"given":"Dmitry","family":"Polevoy","sequence":"first","affiliation":[{"name":"Federal Research Center Computer Science and Control RAS, 119333 Moscow, Russia"},{"name":"Smart Engines Service LLC., 117312 Moscow, Russia"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-9469-8389","authenticated-orcid":false,"given":"Danil","family":"Kazimirov","sequence":"additional","affiliation":[{"name":"Smart Engines Service LLC., 117312 Moscow, Russia"},{"name":"Institute for Information Transmission Problems RAS, 127051 Moscow, Russia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8261-082X","authenticated-orcid":false,"given":"Marat","family":"Gilmanov","sequence":"additional","affiliation":[{"name":"Smart Engines Service LLC., 117312 Moscow, Russia"},{"name":"Institute for Information Transmission Problems RAS, 127051 Moscow, Russia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5560-7668","authenticated-orcid":false,"given":"Dmitry","family":"Nikolaev","sequence":"additional","affiliation":[{"name":"Federal Research Center Computer Science and Control RAS, 119333 Moscow, Russia"},{"name":"Smart Engines Service LLC., 117312 Moscow, Russia"}]}],"member":"1968","published-online":{"date-parts":[[2025,10,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Weber, L.M., Saelens, W., Cannoodt, R., Soneson, C., Hapfelmeier, A., Gardner, P.P., Boulesteix, A.L., Saeys, Y., and Robinson, M.D. (2019).
