Using monochromatic synchrotron radiation and a high resolution x-ray sensing pickup tube as a two-dimensional detector, we have improved the spatial resolution of x-ray computed tomographic (CT) images. A quantitative elemental analysis was made based on the difference between two CT images measured just above and below an element's absorption edge energy. The developed CT imaging system has been used to observe nondestructive fine structures, such as cracks, in a ceramic material. High resolution of 10 μm was obtained. The differential CT value, which was seen as the shading intensity in the differential CT image, was proportional to the concentration of the specific element.
