Opis

Over the last few years, there has been a growingneed to advance the use of thermal ablation therapyas a minimally invasive technique in cancermanagement. Consequently, this work was done toinvestigate the use of hyperthermia and hypothermiaby developing economical probes that will effectively destroy volumes of pathologicaltumours. While work on the cryotherapy probe is stillon-going, the RF thermal probe was tested ondifferent tissues and evaluated for effectivetissue destruction capability. The results show that,at power settings of 20 watts for soft tissue, 13watts for kidney tissue, 6 watts for liver tissue, 3watts for brain tissue and 2 watts for lung tissue,the RF thermal probe effectively destroys volumes ofpathological tumours within a temperature range of 50to 100 degrees centigrade during a 15-minute treatment time. This work should help shed more light on the two energy-based treatment methods investigated, and should be of particular interest to interventional radiologists, researchers in the field of thermal ablation therapy, and cancer patients who are considering the use of energy-based therapy as alternative treatment methods.
