Journal ArticleDOI
X-ray imaging and analysis techniques for quantifying pore-scale structure and processes in subsurface porous medium systems
TL;DR: X-ray microtomographic imaging is a non-destructive technique for quantifying these processes in three dimensions within individual pores, and as reported here, with rapidly increasing spatial and temporal resolution.
Journal ArticleDOI
Image processing of multiphase images obtained via X-ray microtomography: A review
TL;DR: In this article, the authors focus on multiclass segmentation and detailed descriptions as to why a specific method may fail together with strategies for preventing the failure by applying suitable image enhancement prior to segmentation.
Journal ArticleDOI
Techniques for image enhancement and segmentation of tomographic images of porous materials
TL;DR: In this paper, a three-stage approach combining novel and traditional algorithms for the segmentation of images of porous and composite materials obtained from X-ray tomography is presented. But this approach is not suitable for large-scale images.
Journal ArticleDOI
Assessment of bone ingrowth into porous biomaterials using MICRO-CT
Anthony C. Jones,Christoph H. Arns,Adrian Sheppard,Dietmar W. Hutmacher,Bruce Milthorpe,Mark Knackstedt +5 more
TL;DR: It is observed that bone ingrowth occurs primarily at the periphery of the scaffolds with a constant decrease in bone mineralization into the scaffold volume, illustrating the benefits of microtomography for analyzing the 3D structure of scaffolds and the resultant bone ing growth.
Journal ArticleDOI
Morphological clues to wet granular pile stability
Mario Scheel,Ralf Seemann,Martin Brinkmann,M. Di Michiel,Adrian Sheppard,B Breidenbach,Stephan Herminghaus +6 more
TL;DR: This work shows that the remarkable insensitivity of the mechanical properties to the liquid content is due to the particular organization of the liquid in the pile into open structures, and presents evidence that this concept is also valid for systems with non-spherical grains.
