Multi–Frequency Analysis For Interstitial Microwave Hyperthermia Using Multi–Slot Coaxial Antenna

Study on Interstitial Microwave Hyperthermia with Multi-slot Coaxial Antenna

This study focuses attention on interstitial microwave hyperthermia, which is a popular medical procedure for treatment of pathological human tissues containing tumors. In the paper, the 2D finite element analysis is used to compare the models of the coaxial antenna with one, two and three air slots. The implemented models are based on the wave equation in the TM mode coupled with the Pennes eq...

Improvement of Heating Pattern of the Coaxial-slot Antenna for Interstitial Microwave Hyperthermia

A coaxial-slot antenna for invasive microwave hyperthermia therapy

When the technique of invasive microwave hyperthermia is applied to cancer treating, the distribution of microwave thermal field and the effect of the therapy are determined by the type of microwave radiative antenna. The thermal field of biological tissue produced by microwave radiative antenna is investigated in this paper. The distribution of thermal field and specific absorption rate (SAR) ...

Development and Analysis of Coaxial Slot Antenna in Comparision with Coaxial Dipole Antenna for Interstitial Microwave Ablation

Hepatocellular carcinoma (HCC) is the most common malignant tumors to affect the liver. Microwave ablation is efficiently used for treatment of liver cancer. Although surgical resection remains the gold standard for treatment of liver cancer, but only 5-10% patients are the candidates for surgical resection due to numbers of limitations. Because most patients with HCC can not be treated with su...

Coaxial Slot Antenna Design for Microwave Hyperthermia using Finite- Difference Time-Domain and Finite Element Method

Hyperthermia also called thermal therapy or thermotherapy is a type of cancer treatment in which body tissue is exposed to high temperatures. Research has shown that high temperatures can damage and kill cancer cells, usually with minimal injury to normal tissues. Otherwise, ablation or high temperature hyperthermia, including lasers and the use of radiofrequency, microwaves, and high-intensity...
