Microwave Interstitial Helix Applicators for Hyperthermia Cancer Treatment

Popis výsledku v původním jazyce

In this paper we would like to present some of our results in the area of microwave interstitial helix applicators for hyperthermia cancer treatment. We studied the possibilities to create arrays of interstitial applicators as well. The applicators used in this work are the helix type and the operating frequency was 2.45GHz. For our studies based on numerical simulations two types of breast phantoms were used. The interstitial applicators, virtually organized in several configurations, were gradually inserted into these phantoms. The first model of breast was simply created by spherical segment. It was formed by three parts: a homogeneous breast tissue, skin and a spherical tumour. The second breast phantom was derived from magnetic resonance images (MRIs) and includes more parts which are anatomically realistic. The phantom includes a bit more complex shape of the tumour. For calculation of SAR characteristics created by these applicators a simulator of EM field SEMCAD X was used. A distribution of SAR value was especially monitored in the area where the breast tumour was placed. So we could compare the differences between the simplified breast model and the MRI-derived model. As an example of our results we would like to describe numerical simulation of our applicators placed in heterogeneous phantom. This configuration is with four applicators in 10mm distance between each other, see pleas the figures below.
