Effect of the X-ray shooting angles for 2-D images on CT images

In this paper, a new method for the exact reconstruction of any gray-scale image from its projections is proposed. The original X-ray image is projected into several view shooting angles and then 2-D images will be reconstructed to CT images using Matlab software. The main aim of this study was to evaluate the effect of the X-ray shooting angles for 2-D images on CT images and another objective of this study was to obtain 2D X-ray images of CT reconstruction with ordered subsets expectation-maximization (OSEM) method.
