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诊断涂药器的演变

这项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施加器。兼容 MR 的 MW 涂药器能够通过介电对比度测量区分肿瘤组织和健康组织，优化涂药器在病灶中的定位。由于强大的涂药器设计和消融期间产生的介电常数跟踪，甚至可以检测到碳化组织。与市售的涂抹器相比，使用 5 至 10 GHz 的工作频率可显着降低微波消融的功耗，仅为 20 W。消融区的临床相关尺寸可以使用 MR 成像和温度计来实现和额外监测。
