CT System Parameters Determination based on Calibration Method

Ling Liu, Hao Tang, Yuhan Zhou, Jun Ye

Abstract: Parameter calibration of the installed CT system can reduce the error and improve the imaging quality. Based on the geometric information of the known calibration template, the corresponding absorption rate and the received information, three calibration parameters are obtained by Matlab software programming based on the formulas of Radon transformation and Radon inverse transformation 180 directions of the X-ray used by the CT system, the detector The distance between units, the center of rotation of the CT system in the square pallet.

Keywords: CT system, parameter calibration, Radon transformation, Radon inverse transformation
