射频消融治疗是肿瘤局部透热治疗的一种 ,以影像引导或直接将电极针导入肿瘤组织 ,通过射频在电极针周围产生极性分子震荡导致发热 ,使治疗区域的温度达到 5 0℃以上 ,中央区域可达 10 0℃以上 ,使局部细胞坏死 ,达到治疗肿瘤的目的。近年研制出的多种射频治疗系统 ,明显提高了
Radiofrequency ablation is a kind of local hyperthermic treatment of the tumor. Image guidance or direct introduction of the electrode needle into the tumor tissue generates the heat by the polar molecular oscillation around the electrode needle through the radiofrequency, so that the temperature in the treatment area reaches over 50 ° C, The central region up to 10 0 ℃ above, so that local cell necrosis, to achieve the purpose of treatment of cancer. In recent years, the development of a variety of radio frequency treatment systems, significantly improved
