Development of 3D‐CT System Using MIRRORCLE‐6X

The technique of computed tomography (CT) has been used in various fields, such as medical, non‐destructive testing (NDT), baggage checking, etc. A 3D‐CT system based on the portable synchrotron “MIRRORCLE”‐series will be a novel instrument for these fields. The hard x‐rays generated from the “MIRRORCLE” have a wide energy spectrum. Light and thin materials create absorption and refraction contrast in x‐ray images by the lower energy component (< 60 keV), and heavy and thick materials create absorption contrast by the higher energy component. In addition, images with higher resolutions can be obtained using “MIRRORCLE” with a small source size of micron order. Thus, high resolution 3D‐CT images of specimens containing both light and heavy materials can be obtained using “MIRRORCLE” and a 2D‐detector with a wide dynamic range. In this paper, the development and output of a 3D‐CT system using the “MIRRORCLE‐6X” and a flat panel detector are reported.A 3D image of a piece of concrete was obtained. The detect...
