The new method for constructing 3D image from the projection date, which contain noise, obtained from clinical model of limited cone-beam X-ray CT (3DX Multi Image Micro CT) is proposed. Authors proposed the method based on the decomposition in a 2D image from many directions. This paper describes the modified method for improving the processing time keeping visual quality. It is shown that clear 3D image can be obtained by the proposal method with reasonable processing time.
