ABSTRACT
Different factors may influence the image quality of the first generation computed tomography (CT) system (single-source-single-detector) and one of these factors is the object motion. For studying this effect on image quality, an industrial CT system was designed and developed. Several experiments were performed with different axial and rotational motion of a phantom. The quality of reconstructed images was compared by computing the RMSE of each image. Also, in this paper a processing technique is presented that has the potential to detect the object motion during the acquisition process and to correct it by rescanning from motion point. The presented results can be extended to other medical and industrial applications.

    Wavelet transform based de-noising like wavelet shrinkage, gives the good results in CT. This procedure affects very little the spatial resolution. Some applications are reconstruction methods, while others are a posteriori de-noising methods. De-noising after reconstruction is very difficult...
