Numerical Simulation of Thermal Ablation Process for Removal of Tumor Tissues

This research study investigates a novel approach for tumor ablation, focusing on the impact of ferromagnetic thermoseeds on thermal energy generation within human tissue, and explores the effects of these thermoseeds on the transient and steady-state thermal behavior of three distinct materials: Nitinol, Palladium, and Platinum. Considering diverse operational conditions and varying tumor physical characteristics, this study reveals that a higher lethal radius is achieved when tissue thermal conductivity (kt) is greater than 0.5 W/m K and thermoseed heat generation (ġts) is greater than 2 W. Reducing kt and ġts values consistently decreases the lethal radius across all materials. Interestingly, transient analysis demonstrates that the thermal conductivity of the thermoseed has very less significant impact initially; however, Nitinol takes longer to reach a steady state than palladium and platinum. This study helps to understand how to use ferromagnetic thermoseeds better for treating tumors, showing that the material choice and conditions are essential for effective cancer treatment.
