Radiographic Density Of Selected Materials At Different Thicknesses, Thien Quang Vu-Nguyen, Bernice Mills
Radiographic Density Of Selected Materials At Different Thicknesses, Thien Quang Vu-Nguyen, Bernice Mills
STAR Program Research Presentations
X-rays are widely used in medicine and materials science to identify impurities or fractures within the target object. In material science, x-rays can be used to identify the thickness of samples with different material densities. The current method is to collect a radiograph using estimated conditions, evaluate the results, then make changes to the conditions. The residual image can be rescanned making it possible to obtain an image of lower radiographic density. By tabulating or graphing the effects of energy changes and rescans, a more informed choice of conditions is possible.
For this study, six materials were chosen with a …

STAR Program Research Presentations
Solid materials can now be viewed non-destructively with x-rays by tomography; a technique for taking many 2D images of an object at many angles and reconstructing the images into a 3D data cube. The data is next rendered into 2D or 3D still images or movies. By nature, x-ray tomography yields a very large amount of data in three dimensions. Effectively displaying this data to an audience is a challenge.
In this work techniques are explored to improve the presentation methods of movies of both 2D and 3D tomographic data for visual appeal and correct perspective. Finding the optimal ways …
