Analysis of High Frequency Curved Plate Applicator for Deep Hyperthermia in Breast Cancer Treatment by Using Dielectric Heating

摘要

In this paper, we present the curved plate applicator for deep hyperthermia cancer treatment by using dielectric heating. To determine the heat distribution in the breast phantom and cancer cells, the electric loss density was analyzed in the cancer cells location inside the heat area. This heating technique was implemented based on the electric field using the electrode plate applicator was excited by 2.45 GHz. The cancer cells position was located at location (0, 0, 15) of breast phantom. Simulation results show that the heating efficiency area is related to the plate shape. The maximum heating area was close to the cancer cells at the midpoint position that it can heat the deep and narrow for cancer cells.
