| Outline of Final Research Achievements |
X rays in clinical use are white x rays that have broad energy band, so the strict energy selection is impossible. Then, I attempted a diffraction method for generated monochromatic x rays. The diffracted monochromatic x rays are produced by Bragg diffraction on a silicon single crystal and are imaged as Laue spot on the reflected position. However, it is so difficult to detect of Monochromatic x-rays because of their low dose. Recently, the image detectors i.e. Flat Panel Detector, have higher sensitivity and detectability, so the monochromatic imaging is proceeded. Therefore, the monochromatic Computed Tomography and K-edge subtraction technique is performed by my trial research.
