Abstract

In this paper, to determine parameters of the CT system and reconstruct images, the geometric model of the template is used to calculate its parameters, and the image is reconstructed based on the Filtered back projection algorithm, which contains the RADON inverse transform and the usage of calibrated CT system parameters. To remove the noise of the image background, we optimize the image of CT with discrete properties of pixels. What is more, this paper presents a new template that is more appropriate to determine CT system parameters. And it is more conducive to calculating the unit spacing and the receiving angle of detectors, and therefore this new system improves the calibration accuracy of CT system parameters.
