主　　题：Monte Carlo simulation Muon tomography Image reconstruction 

摘      要：Muon tomography is a novel method for the non-destructive imaging of materials based on muon rays,which are highly penetrating in natural background ***,the most commonly used imaging methods include muon radiography and muon tomography.A previously studied method known as coinciding muon trajectory density tomography,which utilizes muonic secondary particles,is proposed to image low and medium atomic number(Z)***,scattering tomography is mostly used to image high-Z materials,and coinciding muon trajectory density tomography exhibits a hollow phenomenon in the imaging results owing to the self-absorption *** address the shortcomings of the individual imaging methods,hybrid model tomography combining scattering tomography and coinciding muon trajectory density tomography is proposed and *** addition,the peak signal-to-noise ratio was introduced to quantitatively analyze the image *** imaging models were simulated using the Geant4 toolkit to confirm the advantages of this innovative *** simulation results showed that hybrid model tomography can image centimeter-scale materials with low,medium,and high Z *** high-Z materials with similar atomic numbers,this method can clearly distinguish those with apparent differences in *** to the peak signal-to-noise ratio of the analysis,the reconstructed image quality of the new method was significantly higher than that of the individual imaging *** study provides a reliable approach to the compatibility of scattering tomography and coinciding muon trajectory density tomography.
