| Research Abstract |
This study developed software for the reduction of moving artifacts due to breathing in rats by means of teeth tracking when CT images were taken using in vivo micro-computed tomography (CT).Raw projection data from the CT of teeth in rats were chosen retrospectively, which were then correlated with moving artifacts due to breathing. An m-mode image was reconstructed from the projection data, which was used to calculate motion as a function of position. The projection data were corrected and CT images were reconstructed using the corrected projection data.The artifacts were reduced using this software.
