This paper describes through computer simulation the utilization of the interstitial microwave hyperthermia in the treatment of pathological tissues. Electromagnetic field, radiated from coaxial-slot antenna is used to produce a temperature gradient in human tissue. Therefore the presented issue is a coupling of the electromagnetic field and the temperature field. For simplification a 2D model is...
The presented paper shows a new concept of multi-slot coaxial antenna working at different frequencies to predict the best solution for interstitial microwave hyperthermia treatment. The described method concerns a microwave heating of unhealthy cells using a thin microwave antenna located in the human tissue. Therefore, the coupled wave equation in a sinusoidal steady-state and the transient bioheat...
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 equation...
Śródmiąższowa hipertermia mikrofalowa jest inwazyjną metodą leczenia, w której grzanie elektromagnetyczne jest wytwarzane przez różnego rodzaju aplikatory mikrofalowe umieszczone wewnątrz chorych tkanek. Dobry przykład może stanowić współosiowa antena ze szczeliną powietrzną przedstawiona w niniejszej pracy. Opisany 2D model matematyczny stanowi połączenie elektromagnetycznego równania falowego dla...
