Abstract

In this paper, we use the known template to calibrate the parameters of the two-dimensional CT system. The calibration of CT system includes three aspects: the location of the center of the system in the square pallet, the distance between the detector units, and the 180 directions of the X-ray used by the system. First, the CT system is abstracted. Then, we have established the Descartes coordinate system, and the quantitative processing of the CT system is based on this coordinate system. The final solution is: The location of the center of the system is (-9.1034, 5.7931). The distance between the detector units is 0.2759. The CT system is evenly rotated and the rotation angle is 1°. The original angle is -60°.Finally, we give evaluation to our model, followed by a brief remark about our work
