Nanoparticles in enhancing microwave imaging and microwave Hyperthermia effect for liver cancer treatment

Abstract Hyperthermia therapy is a promising for liver cancer treatment that utilizes external electromagnetic waves to heat the tumor zone preferentially kill or minimize cells. Nevertheless, it’s challenge realize localized heating of tissue without harming surrounding healthy tissue. This research proposes utilize nanoparticles as microwave absorbers enhance imaging and achieve hyperthermia therapy. A realistic 3D abdomen model has been segmented using Slicer segmentation software, then obtained CAD exported Computer Simulation Technology (CST STUDIO) applying Finite Element Modeling (FEM). Next investigating both capability. Finally, specific absorption rate (SAR) temperature distribution were computed with different types such gold (GNPs) silver at frequency 915 MHz. By comparing achived results, it was seen Silver can make great enhancement in raising temperature. However, this result unsatisfactory but, after adding exceed 42°C, MHz which achieving nearby tissue, GNPs also SAR
