Outline of Final Research Achievements |
Detecting a three-dimensional (3D) distribution of a specific element has been experimentally demonstrated using the parametric X-ray (PXR) source at Nihon University. Based on the K-shell edge subtraction (KES) method, the 3D-distributions of Sr element in the samples were obtained as computed tomography (CT) images. First, 2-color CT experiments were independently carried out at the X-ray energies above and below the Sr K-shell absorption edge using tunability of the PXR source. The Sr distribution was obtained from the subtraction between these CT images. Next, the experiment for simultaneous KES-CT was performed using dual-energy crossing beams based on the spectral property of the PXR beam. The result shows that the Sr distribution can be obtained by this unique method.
