Two microwave applicators for intracavitary hyperthermia treatment of cancer colli uteri

Abstract

The authors designed and tested two microwave applicators suitable for intracavitary hyperthermia treatment of advanced cancer colli uteri in combination with ionising radiation. The antennas operate at the frequencies of 2450 MHz and 680 MHz. Hence patients with differing extents of tumour growth along the collum uteri can be treated. The antenna is covered with a PTFE tube to form an applicator. The absorption in the tube is very low, and consequently the power is delivered outside the tube.
