This enables the 3D reconstruction of characteristic morphological features of human pancreatic normal and tumor tissue, as obtained from cancer surgery, first in the form of a large-scale overview by parallel-beam illumination, followed by a zoom into a region-of-interest based on zoom tomography using a Kirkpatrick-Baez mirror with additional waveguide optics. To this end 1 mm punch biopsies of the tissue were taken. In the parallel tomography, a volumetric throughput on the order of 0.01 mm3 s-1 was achieved, while maintaining the ability to segment isolated cells. With a continuous rotation during the scan, a total acquisition time of less than 2 min was required for a full tomographic scan. Using the combination of both setups, islets of Langerhans, a three-dimensional cluster of cells in the endocrine part of the pancreas, could be located. Cells in such an islet were segmented and visualized in 3D. Further, morphological alterations of tumorous tissue of the pancreas were characterized. To this end, the anisotropy parameter Ω, based on intensity gradients, was used in order to quantify the presence of collagen fibers within the entire biopsy specimen. This proof-of-concept experiment of the multiscale approach on human pancreatic tissue paves the way for future 3D virtual pathology."],["dc.description.abstract","This paper presents propagation‐based phase‐contrast tomography in two configurations at the beamline endstation GINIX, demonstrated on the application of 1 mm human pancreatic tumor tissue biopsies. image"],["dc.identifier.doi","10.1107/S1600577520011327"],["dc.identifier.pmid","33147198"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/69419"],["dc.identifier.url","https://mbexc.uni-goettingen.de/literature/publications/85"],["dc.language.iso","en"],["dc.notes.intern","DeepGreen Import"],["dc.publisher","International Union of Crystallography"],["dc.relation","EXC 2067: Multiscale Bioimaging"],["dc.relation.issn","1600-5775"],["dc.relation.orgunit","Institut für Röntgenphysik"],["dc.relation.workinggroup","RG Salditt (Structure of Biomolecular Assemblies and X-Ray Physics)"],["dc.relation.workinggroup","RG Alves (Translationale Molekulare Bildgebung)"],["dc.rights","This is an open access article under the terms of the Creative Commons Attribution License, which permits use,\r\n distribution and reproduction in any medium, provided the original work is properly cited."],["dc.subject.gro","biomedical tomography"],["dc.title","3D virtual histology of human pancreatic tissue by multiscale phase-contrast X-ray tomography"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dspace.entity.type","Publication"]]
