Template calibration and optimization of CT system parameters
There are often errors in the installation of CT systems that can affect the quality of imaging, therefore, it is necessary to calibrate the installed CT system, that is, to calibrate the parameters of the CT system with a sample of a known structure (called a template), and to image the sample of the unknown structure. In this paper, the geometric template of ellipse and circle is selected, the geometric model is geometrically partitioned through geometrical center point to establish an optimization model, and the model is solved by using genetic algorithm, and using radar transform to invert, reconstruct the image to correct the model, and optimize the parameter calibration of the CT system.
