X-RAY SPECTAL DECOMPOSITION IMAGING SYSTEM |
摘要 |
Projection measurements are made of the transmitted x-ray beam in low and high energy regions. These are combined in a non-linear processor to produce atomic-number-dependent and density-dependent projection information. This information is used to provide cross-sectional images which are free of spectral-shift artifacts and completely define the specific material properties. |
