Miniature computed tomography with vertical rotating gantry: Application for 3D modeling

Miniature computed tomography system with vertical rotating gantry is presented in this paper. System calibration was performed before achieving the projection data. An object placed on platform was exposed by the camera every one degrees of rotating angle. Thus, 360 projection data were performed in this study. Finally, Feldkamp algorithm based on a 3-D filtered back projection was employed to reconstruct cross sectional images. The result shows that 3-D model images and volume-rendering obtained from our miniature computed tomography were satisfactory. In conclusion, the miniature computed tomography presented in this study is capable to construct 3-D model with an ease technique.
