A METAL ARTIFACT REDUCTION ALGORITHM IN CT USING MULTIPLE PRIOR IMAGES BY RECURSIVE ACTIVE CONTOUR SEGMENTATION.

A metal artifact reduction algorithm in CT using multiple prior images by recursive active contour segmentation.

We propose a novel metal artifact reduction (MAR) algorithm for CT images that completes a corrupted sinogram along the metal trace region.When metal implants are located inside a field of view, they create a barrier to the transmitted X-ray beam due to the high attenuation of metals, which significantly degrades the image quality.To fill in the me

Investigating the missing-wedge problem in small-angle X-ray scattering tensor tomography across real and reciprocal space

Small-angle-scattering tensor tomography is a technique for studying anisotropic nanostructures of millimetre-sized samples in a volume-resolved manner.It requires the acquisition of data through repeated tomographic rotations about an axis which is subjected to a series of tilts.The tilt that can be achieved with a typical setup is geometrically c

First-principles calculations on dislocations in MgO

While ceramic materials are widely used in our society, their understanding of the plasticity is not fully understood.MgO is one of the prototypical ceramics, extensively investigated experimentally and theoretically.However, there is still controversy over whether edge or screw dislocations glide more easily.In this study, we Round Cake Pans direc

THE NEGROES, ETHNIC-RACIAL DIVERSITY AND SCHOOL: THE DIDACTIC-PEDAGOGIC TREATMENT OF AFRO-BRAZILIAN HISTORY AND CULTURE IN TWO BOOKS OF HISTORY OF BRAZIL IN THE FIRST HALF OF THE TWENTIETH CENTURY

This study aims to examine, from a historical perspective, the relations between ethnic-racial diversity in Brazil and didactic-pedagogic treatment of Afro-Brazilian history and culture in two books, concerning History Brazil, issued in the first half of the twentieth century, assuming that these teaching materials also exercised Round Cake Pans in
