this paper adopts simultaneous iterative reconstruction technique ( sirt) to perform the crosswell tomography based on shortest path tree ( spt) curved ray tracing.

in algebra iterative algorithm we found the range of relaxation parameter is very different. the range of relaxation parameter of art was narrower than that of sirt.

在代数迭代算法中，通过模拟图像的重建发现，ART算法和SIRT算法松弛因子的选择有很大的不同，SIRT的松弛因子选择范围偏小，而ART的松弛因子选择范围要宽得多；
