“…Therefore, in SCM for voxel data, a practicable calculation speed can be obtained without sacrificing the accuracy of numerical surface integration during the preparatory calculation. The flux continuity condition [6] can be satisfied by improvement of the accuracy of numerical surface integration, particularly with regard to the continuity of the normal component of the flux density. Thus, due to the combination of the method of moments with (advantage 2), the flux continuity condition can be satisfied for each element, and as a result, Gauss's theorem can be satisfied globally.…”
