Superimposed single-photon emission computed tomography and X-ray computed tomography of the heart: Methodical aspects

Вестник рентгенологии и радиологии, 2016
Global radiology and nuclear medicine have recently shown a clear trend towards hybrid (combined, superimposed) studies. Unfortunately, the Russian literature virtually lacks both methodological and research works on this topic.

X-ray computed tomography for medical imaging [PDF]

IEEE Signal Processing Magazine, 1997
The article looks at reconstruction in 2-D and 3-D tomography. We have not dealt with some of the issues in reconstruction such as sampling and aliasing artifacts, finite detector aperture artifacts, beam hardening artifacts, etc., in greater detail since these are beyond the scope of an introductory tutorial.

Nondestructive Testing of Welded Composite Metal Foams

Advanced Engineering Materials, EarlyView.
X‐ray computed tomography (CT) is used to evaluate welded steel–steel composite metal foam (CMF) joints of two density classes. It reports variation in postweld spatial void distribution and correlates it to weld‐induced changes, mechanical performance, and failure within welded CMF panels.

An experimental study on segmentation in X-Ray Computed Tomography [PDF]

, 2019
X-Ray Computed Tomography is an emerging technology for geometric inspection, in particular when complex and internal surfaces are involved. The typical work-flow for an X-Ray Computed Tomography inspection includes scanning the part, reconstructing the ...

Development of Dimensional X-Ray Computed Tomography

International Journal of Automation Technology, 2015
Recently, a strong need has arisen for a dimensional X-ray computed tomography system that is capable of dimensional measurements. This is because the speedy realization of dimensional measurements for outward forms and inward forms on dense spatial points remarkably simplifies and accelerates production loop.

Microstructure Reconstruction in Battery Electrodes Using Machine Learning Based on Low‐Voltage Focused Ion Beam–Scanning Electron Microscopy Tomography Images

Advanced Engineering Materials, EarlyView.
Low‐voltage FIB‐SEM tomography combined with a image preprocessing pipeline improves phase contrast and enables reliable machine‐learning segmentation of conductive networks in lithium‐ion battery electrodes. Structural descriptors are extracted from segmented images, done semimanually and automated, and compared.
