X-Ray Computed Tomography of Ultralightweight Metals
Research in Nondestructive Evaluation, 1999In recent years several universities, government laboratories, and private industries have been developing specific process technologies, analytical modeling tools, and characterization methods for highly porous metals and alloys frequently collectively termed ``ultralightweight metals.'' The goal has been to achieve a family of metallic structures ...

Radiation Load in X-Ray Computer Tomography
Biomedical Engineering, 2011Methods for radiation load reduction in helical multidetector X-ray computer tomographs are discussed. The GOST IEC standards and dose monitoring methods should be corrected.

X-ray computed tomography (CT) is still a workhorse of neuroimaging despite the significant contributions to neurodiagnosis made by newer technologies such as magnetic resonance imaging (MRI), positron emission tomography (PET), and single proton emission CT (SPECT). Within only a few years of its introduction in 1972, by Geoffrey N.

The effects of scatter in x‐ray computed tomography
Medical Physics, 1982The effects of detection of scattered radiation in x‐ray transmission CT are studied both theoretically and experimentally. It is shown that scatter induces nonlinear errors in the measurement of attenuation values which can lead to cupping, streaks, and CT number inaccuracies.

Industrial Applications of X-Ray Computed Tomography
Advances in X-ray Analysis, 1987Computed tomography (CT), commonly known as CAT scanning (computerized axial tomography), is a technology that produces an image of the internaI structure of a cross sectional slice through an object via the reconstruction of a matrix of X-ray attenuation coefficients.

Dynamic X-ray computed tomography
Proceedings of the IEEE, 2003Dynamic computed tomography (CT) imaging aims at reconstructing image sequences where the dynamic nature of the living human body is of primary interest. The main applications concerned are image-guided interventional procedures, functional studies and cardiac imaging.

X-ray computed tomography of the cardiovascular system
Current Problems in Cardiology, 1991X-ray CT of the heart is an evolving field. The ultrafast CT scanner provides a practical method of applying the high spatial resolution, high density resolution, and tomographic capabilities of conventional CT scanning, permitting an evaluation of the cardiovascular system.
