Table 1 Tissue and material properties

From: Computer 3D modeling of radiofrequency ablation of atypical cartilaginous tumours in long bones using finite element methods and real patient anatomy

Material/tissue Electrical conductivity (S/m) Blood perfusion coefficient (x 103s1) Density (kg/m3) Specific heat (J/kg ∙ K) Thermal conductivity (W/m/K)
Active electrode a 1.00 R + 08 0 6,450a 840 18
Tumour 0.4 b 0 1,150 3,664 0.487
Trabecular bone 0.05 0.167 1,080 2,060 0.36
