One of the common problems about industrial X-ray CT is metal artifacts. As this countermeasure, in the industrial X-ray CT, a thin metal plate is placed between a sample and a X-ray generator to reduce beam hardening which is one of the contributing factors for metal artifacts. On the other hand, medical X-ray CT utilizes a technique termed Dual Energy CT. In Dual Energy CT, CT imaging is performed with different tube voltages as the mass attenuation coefficient of a sample varies depending on the X-ray energy. Dual Energy CT is more effective in reducing beam hardening than the aforementioned thin metal plate method commonly used in industrial X-ray CT. However, it is not widely used in industrial X-ray CT. In order to verify the effect of Dual Energy on CT data, basic experiments were conducted using the inspeXio SMX-225CT FPD HR Plus (Shimadzu Corp.). |
