Three-dimensional phase-contrast X-ray microtomography with scanning–imaging X-ray microscope optics
A three-dimensional (3D) X-ray tomographic micro-imaging system has been developed. The optical system is based on a scanning-imaging X-ray microscope (SIXM) optics, which is a hybrid system consisting of a scanning microscope optics with a one-dimensional (1D) focusing (line-focusing) device and an imaging microscope optics with a 1D objective. In the SIXM system, each 1D dataset of a two-dime...
متن کامل-Three-Dimensional Images of Snow Bands-
Three-dimensional computer graphic techniques are applied to the processing of snowstorm radar data. The following techniques are examined: 1) perspective representation of radar data; 2) zooming; 3) change in viewing angle and viewing point; 4) arbitrary cross-sectional analysis; and 5) time sequence analysis of perspective

First, X-ray computed to...
متن کاملX-ray microtomography in biology.
Progress in high-resolution X-ray microtomography has provided us with a practical approach to determining three-dimensional (3D) structures of opaque samples at micrometer to submicrometer resolution. In this review, we give an introduction to hard X-ray microtomography and its application to the visualization of 3D structures of biological soft tissues. Practical aspects of sample preparation...
متن کاملHigh resolution three-dimensional visualization and characterization of coronary atherosclerosis in vitro by synchrotron radiation x-ray microtomography and highly localized x-ray diffraction.
Human atherosclerotic plaques in both native and bypass arteries have been visualized using microtomography to provide additional information on the nature of coronary artery disease. Plaques contained within arteries removed from three white males aged 51, 55 and 70 are imaged in three-dimensions with monochromatic synchrotron x-ray radiation. Fields of view are 658 x 658 x 517 voxels. with cu...
