Quantitative X-ray tomography
Eric Maire,Philip J. Withers +1 more
TL;DR: In this paper, the authors review the current state of the art as CT transforms from a qualitative diagnostic tool to a quantitative one, including the use of iterative reconstruction strategies suited to specific segmentation tasks and emerging methods that provide more insight than conventional attenuation based tomography.

Segmentation of X‐ray computed tomography images of porous materials: A crucial step for characterization and quantitative analysis of pore structures
TL;DR: In this paper, the applicability of various thresholding and locally adaptive segmentation techniques for industrial and synchrotron X-ray CT images of natural and artificial porous media was investigated.

Representation of a Function by Its Line Integrals, with Some Radiological Applications
TL;DR: In this paper, a method for finding a real function in a finite region of a plane given its line integrals along all straight lines intersecting the region was given, and the solution found is applicable to three problems of interest for precise radiology and radiotherapy: (1) the determination of a variable x-ray absorption coefficient in two dimensions, (2) the distribution of positron annihilations when there is an inhomogeneous distribution of the positron emitter in matter, and (3) a variable density of matter with constant chemical composition, using the energy loss

The direct examination of three‐dimensional bone architecture in vitro by computed tomography
TL;DR: A measure of three‐dimensional connectivity (Euler number/tissue volume) has been determined for the first time in human cancellous bone and shown to correlate with several two‐dimensional histomorphometric indices.

The relationship between the structural and orthogonal compressive properties of trabecular bone
Robert W. Goulet,Steven A. Goldstein,Michael J. Ciarelli,Janet L. Kuhn,M. B. Brown,Lee Albert Feldkamp +5 more
TL;DR: In this study, cubes of trabecular bone with a wide range of structural properties were scanned on a micro-computed tomography system to produce complete three-dimensional digitizations from which morphological and architectural parameters could be measured in a nondestructive manner and a high correlation between the basic stereologic measurements was found.
