A matched-dipole type catheter antenna is described for intracavitary and/or transluminal microwave treatment of diseases that may be responsive to thermal ablation therapy. This cap-choke antenna consists of an annular cap and coaxial choke design that can yield SAR distributions in and can produce heating of tissue surrounding the distal end of the catheter antenna. The cap-choke antenna is simple in construction, provides the desired specific absorption rate (SAR) distribution, and is efficient, i.e., the measured power reflection coefficient is 2% in tissue equivalent phantom modeling materials.
本文描述了一种匹配偶极型导管天线，用于对热消融疗法可能有反应的疾病进行腔内和/或经腔微波治疗。这种帽式扼流圈天线由环形帽和同轴扼流圈设计组成，能够在导管天线远端周围的组织中产生比吸收率（SAR）分布并使组织发热。帽式扼流圈天线结构简单，能提供所需的比吸收率（SAR）分布，且效率高，即在组织等效体模建模材料中测得的功率反射系数为2%。
