F-18-FDG Uptake and Calcifications in the Thoracic Aorta on Positron Emission Tomography/Computed Tomography Examinations Frequency and Stability on Serial Scans
(Lippincott Williams & Wilkins, 2011-02-01)
Purpose: Vascular F-18-2-fluoro-2-deoxy-D-glucose (F-18-FDG) uptake has been suggested as a means of identifying metabolically active atheroma, whereas vascular calcification is accepted as an indicator of atherosclerosis. ...
Validation of cone-beam computed tomography and magnetic resonance imaging of the porcine spine: a comparative study with multidetector computed tomography and anatomical specimens
(Elsevier B.V., 2015-05-01)
BACKGROUND CONTEXT: New spinal interventions or implants have been tested on ex vivo or in vivo porcine spines, as they are readily available and have been accepted as a comparable model to human cadaver spines. Imaging-guided ...
Reconstructing 3-colored grids from horizontal and vertical projections is NP-Hard: a solution to the 2-Atom problem in discrete tomography
(SIAM PUBLICATIONS, 2012)
We consider the problem of coloring a grid using k colors with the restriction that each row and each column has a specific number of cells of each color. This problem has been known as the (k - 1)-atom problem in the ...
Effects of four instruments on coronal pre-enlargement by using cone beam computed tomography
(ElsevierPorto Alegre, 2010)
Introduction: This ex vivo study used cone beam computed tomography to evaluate the amount of dentin removal from the distal wall of the mesial canal of human mandibular first molars caused by 4 instruments used to flare ...
Application of computed tomography images in the evaluation of magnetic nanoparticles biodistribution
(ELSEVIER SCIENCE BV, 2010)
In this work we evaluate the effectiveness of computed tomography images as a tool to determine magnetic nanoparticle biodistribution over biological tissues. For this purpose, tomography images for magnetic nanoparticles, ...
Epipericardial Fat Necrosis: Sonographic Findings and Their Correlation With Computed Tomography
(John Wiley & Sons, 2016)
Epipericardial fat necrosis is a rare cause of chest pain. It presents as pleuritic pain in an otherwise healthy patient. Computed tomography has proved to be the most effective diagnostic imaging technique because of its ...

Non-conventional applications of computerized tomography: Analysis of solid dosage forms produced by pharmaceutical industry
(2010-08-26)
X-ray computed tomography (CT) refers to the cross-sectional imaging of an object measuring the transmitted radiation at different directions. In this work, we describe a non-conventional application of computerized ...

New experimental set up for ACB tomography
(2015-01-01)
New tomographic methods for the formation of free ionizing radiation has attracted great interest in the last decades, including the biosusceptometry AC tomography has important characteristic that can be exploited for the ...
