Abstract

Abstract The purpose of this work is to further develop a novel dual-mode microwave applicator for diagnosis and thermal ablation treatment. The MR-compatible MW applicator enables differentiation of tumor tissue and healthy tissue through dielectric contrast measurements, optimizing the positioning of the applicator in the lesion. Due to the robust applicator design and the resulting permittivity tracking during ablation, even carbonized tissue can be detected. The use of operating frequencies between 5 and 10 GHz allow a noticeably lower power consumption for microwave ablation of only 20 W compared to commercially available applicators. Clinically relevant dimensions of ablation zones can be achieved and additionally monitored using MR imaging and thermometry.

用于微波消融治疗的治疗探头的发展

摘要本工作的目的是进一步开发一种用于诊断和热消融治疗的新型双模微波辐射器。MR兼容的MW涂抹器能够通过介电对比度测量区分肿瘤组织和健康组织，优化涂抹器在病变中的定位。由于坚固的涂抹器设计和消融过程中产生的介电常数跟踪，甚至可以检测到碳化组织。与商业上可获得的施加器相比，使用5GHz和10GHz之间的工作频率允许仅20W的微波消融的功耗显著降低。消融区的临床相关尺寸可以使用MR成像和测温来实现和额外监测。

期刊介绍： Frequenz is one of the leading scientific and technological journals covering all aspects of RF-, Microwave-, and THz-Engineering. It is a peer-reviewed, bi-monthly published journal. Frequenz was first published in 1947 with a circulation of 7000 copies, focusing on telecommunications. Today, the major objective of Frequenz is to highlight current research activities and development efforts in RF-, Microwave-, and THz-Engineering throughout a wide frequency spectrum ranging from radio via microwave up to THz frequencies. RF-, Microwave-, and THz-Engineering is a very active area of Research & Development as well as of Applications in a wide variety of fields. It has been the key to enabling technologies responsible for phenomenal growth of satellite broadcasting, wireless communications, satellite and terrestrial mobile communications and navigation, high-speed THz communication systems. It will open up new technologies in communications, radar, remote sensing and imaging, in identification and localization as well as in sensors, e.g. for wireless industrial process and environmental monitoring as well as for biomedical sensing.
