The temperature distribution in the human head and the variation curve of the temperature increase with different pulse total number. (a) n = 400, (b) n = 800, (c) n = 1600, (d) n = 3200, (e) n = 4800, (f) n = 6600, (g) the variation curve of the temperature increase. We used COMSOL Multiphysics software, version 5.4 (https://www.comsol.com/comsol-multiphysics) for simulation results (Images a–f) and Origin software, version 8.0 (https://www.originlab.com/index.aspx?go=Products/Origin) for data analysis (Image g).
