肿瘤的热疗法是当前肿瘤放疗、化疗的有效辅助疗法。影响肿瘤的微波热疗效果的决定性因素是微波能量在肿瘤组织中的合理分布,如何提高微波辐射器的辐射效率,将辐射的微波能聚焦在肿瘤体是当前辐射器研究的重点。文中针对国内外已研制的微波热疗辐射器,从单辐射器和辐射器阵列两个方面综述辐射器聚束的方法及研究工作进展。 Tumor heat therapy is the current tumor radiotherapy, chemotherapy, effective adjuvant therapy. The decisive factor that affects the effect of microwave hyperthermia is the rational distribution of microwave energy in tumor tissue. How to improve the radiation efficiency of microwave radiators and focus the microwave energy of the radiation on the tumor is the current research focus of radiators. In this paper, the microwave hyperthermia radiators developed at home and abroad are reviewed. The methods and research progress of the radiators are summarized from two aspects: single radiator and radiator array.
