Research on tomographic image reconstruction algorithms based on fixed-point rotation X-CT system

Aiming at the problem of parameter calibration and image reconstruction of typical two-dimensional CT system, this paper uses back projection, iradon function, Fourier transform, Lambert law, visualization and other methods to establish projection centroid model, convolution back projection model, TV constrained iterative filtering back projection model, and uses MATLAB, Solidworks, Lingo and other software to visualize data types, so as to achieve better results. Better to find X-CT system tomography reconstruction methods.
