This study is an investigation into the ability of ferromagnetic thermal therapy to destroy cancerous hepatic tissue. Ferromagnetic rods are implanted in cancerous tissue and heated by induction. Increased temperatures result in tumor destruction. Because alloy implants are minimally invasive, used for multiple treatments and are temperature self-regulating, they represent a superior cancer treatment compared to many alternatives. The focus of modeling ferromagnetic thermal therapy will be to maximize tumor obliteration by considering heating temperature and the placement of alloy rods. Data on the efficacy of different Curie points and probe arrangements as well as sensitivity to variations in material properties are presented. Recommendations are made for the implementation of this treatment based on the modeled results.
