The Optimization of Non-invasive Focused Deep Hyperthermia Inductive Heating for Breast Cancer Treatment by Using Nanoparticles and Magnetic Shielding System

The optimization of noninvasive focused deep hyperthermia inductive heating with nanoparticles injected and magnetic shielding system for breast cancer treatment has been presented in this article and the results are discussed. It is a technique to control magnetic field intensity and focusing the heating area by using magnetic fluid and cylindrical metal shielded with aperture. To focusing and increase the heating efficiency in the breast cancer treatment. In the simulation, the inductive applicator is a ferrite core with diameter of 7 cm and excited by 4 MHz signal. We show that the magnetic field intensity can be controlled by changing the aperture size to suitable. The simulations show that the heating area can be effectively controlled by using the magnetic fluid together with shielding system. Results have shown that the efficiency of heat can be increased by varying the radius size of shielding. Moreover, we show that the heating efficiency can be increased by using the magnetic fluid nanoparticles. The advantage of proposed magnetic field shielding system with nanoparticles injected is that it can be applied to non-invasive focused deep hyperthermia inductive heating for breast cancer treatment.
