Research on reconstruction qlgorithm of cosmic ray muon tomography

Image reconstruction algorithm is an important part in muon tomography imaging techniques. This paper introduced the basic principle of cosmic ray muon tomography based on multiple Coulomb scattering, studied the principle and method of muon tomography imaging algorithm. With the comparison of the imaging results, this paper analyzed the characteristics of various algorithms, summarized the advantages and disadvantages of different algorithm in imaging precision and operation speed, and explored the future developing trend of muon tomography imaging algorithms.
