Thermal energy must be properly controlled to avoid the extensive thermal damage of the normal bio tissue during the medical laser therapy. In the process of the laser surgery, laser heat sources may apply as the multiple-points around the specific target that the distance among these multiple-points are very close. The thermal energies may accumulate due to the effects of the interactions among these multiple heat points. The thermal damage of normal bio tissue may be earlier than the traditional estimation using the single damage criterion. Thus, the aim of this paper presents the safety criteria for the distance among the multiple-points of the laser source applied. In this study, laser heat source at the specific point is also considered as Gaussian distributions and simulated as the double ellipsoid function. The bio-heat transfer finite element methodology considering the interactions among multiple laser heat sources is successfully developed herein.
