Abstract

Magnetic induction hyperthermia is one of hopeful methods for tumor therapy. In this method, several ferromagnetic seeds are needed to be implanted into the tumor. The seeds would produce energy, and cause the nearby tumor to die. Temperature prediction is significant before treatment. In addition, in clinical treatment, the tumor temperature has to be monitored in realtime. However, using as few thermometers as possible is the basic principle. Fortunately, the numerical simulation can contribute to realtime measurement. The seed temperature is modeled based on the Haider's method, which is treated as the thermal boundary in numerical simulation. We employ the lattice Boltzmann method to solve the bio-heat transfer equation. Meanwhile, three phantom experiments are carried out to evaluate the model. Thirty-two thermal seeds in total were implanted into a phantom, and three thermocouples are embedded into the specific positions to record the variation of temperature. By comparing the results of simulations and experiments, we obtain that the proposed numerical model is effective.
