Abstract

This paper solves the problem of how to calibrate the parameters of a CT system with a structure-known template. We used the method of radon inverse transformation. The calibration parameters include three aspects: the distance of the detector unit, the rotation center of the CT system in the square tray position, and the direction of the X-ray. The detector unit spacing is 0.2759mm. The position of the rotation center of the CT system in the square tray is (-9.3806,5.5180).The initial angle of X-ray is 30.0400° for each increase 1°. At the end, this paper analyzes the error and obtains the rationality of its results.
