Název v původním jazyce

A Single Helical Interstitial Applicator for Microwave Hyperthermia

Popis výsledku v původním jazyce

This article presents the design and experimental evaluation of a single helical interstitial applicator for localised microwave hyperthermia treatment. The applicator operates at a frequency of 2.45 GHz and is intended to treat small tumours with a 2–3 cm diameter located under the skin. The study includes numerical simulations in Sim4Life focusing on the distribution of the specific absorption rate (SAR) and the reflection coefficient |s11|. The designed applicator was manufactured and tested using an agar phantom with dielectric and thermal properties similar to human muscle tissue. Experimental results confirm efficient energy delivery with a measured reflection coefficient of -46.5 dB and a controlled thermal response. This research supports the potential of single-antenna hyperthermia for interstitial cancer treatment. At the same time, the optimised applicator can be used in the design of a more complex hyperthermia system.
