(a) Case Comparison for Total Power Absorption in Treated Tumor Region after Optimization. PBHTE is the case when no blood vessel presents. And the case of CBVN has the same blood perfusion rate as the PBHTE case but includes a network of vessels which reveal blood flow rate about 320 mm/sec in level 1 artery and vein vessels. The perfusion rate of 0.5 kg/(m3s) in tissues which are perfused by blood vessels is used for PBHTE. 7(b) The comparison of temperatures along level 5 and level 6 vessel segments after optimization at middle plane of the heated region (arterial route: from 0 to 0.02 m; veinous route: from 0.02 to 0) in case of CBVN model (level5-6a represents arterial path consists of level 5 and level 6 vessels; level5-6v represents veinous path consists of level 5 and level 6 vessels) and those temperatures in case of PBHTE model (level5-6a PBHTE represents those arterial path locations which are calculated via PBHTE instead of CBVN; level5-6v PBHTE represents those veinous path locations which are calculated via PBHTE instead of CBVN). 7(c) Lengthwise coordinate (indicated by a dash line) from the intersection of level 3-4-5 vessels to the level 6-7 intersection at the middle plane of heated region shown in Fig. 2(a)
