X-ray luminescence computed tomography using a focused X-ray beam [PDF]
, 2017 Due to the low X-ray photon utilization efficiency and low measurement sensitivity of the electron multiplying charge coupled device (EMCCD) camera setup, the collimator based narrow beam X-ray luminescence computed tomography (XLCT) usually requires a long measurement time.

A Variational Beam Model for Failure of Cellular and Truss‐Based Architected Materials
Advanced Engineering Materials, EarlyView., 2023 Herein, a versatile and efficient beam modeling framework is developed to predict the nonlinear response and failure of cellular, truss‐based, and woven architected materials. It enables the exploration of their design space and the optimization of their mechanical behavior in the nonlinear regime. A variational formulation of a beam model is presented

Design for X-Ray Computed Tomography
Procedia CIRP, 2019 Abstract The search for higher and higher performance is pushing part geometry to increased complexity. A significant contribution to this trend has been given by the diffusion of additive manufacturing technologies: substituting a simple additive manufacturing part with a complex one does not significantly affect the production cost.

Advanced Engineering Materials, EarlyView., 2023 A novel method for tracking structural changes in gels using widely accessible microcomputed tomography is presented and validated for various hydro‐, alco‐, and aerogels. The core idea of the method is to track positions of micrometer‐sized tracer particles entrapped in the gel and relate them to the density of the gel network.

Three dimensional image correlation from X-Ray computed tomography of solid foam [PDF]
Composites A: Applied Science and Manufacturing (2007) 0, 2007 A new methodology is proposed to estimate 3D displacement fields from pairs of images obtained from X-Ray Computed Micro Tomography (XCMT). Contrary to local approaches, a global approach is followed herein that evaluates {\em continuous} displacement fields.

Translation: About one scheme of tomography [PDF]
arXiv, 2020 The translation of an early (1958), Russian article by B. I. Korenblum, S. I. Tetelbaum and A. A. Tyutin on the development of x-ray computed tomography is provided. A new method to acquire cross-sectional x-ray images is studied which is based on processing information contained in an x-ray sinogram recorded at varying angles of an object.
