Table 2.

Source reconstructed position comparisons between DA and SP₃ approximation. (FM: Fine mesh, Multiview; CM: Coarse mesh, Multiview; FS: Fine mesh, Single view; Reconstruction: the center position of reconstructed source; Relative Errors: the absolute distance between the reconstructed and actual positions at X-, Y-, and Z-axis directions; Distance: the absolute distance between the reconstructed and actual positions)
