侵入式微波天线热疗性能研究

Research on the Hyperthermia-Therapy Performances of Invasive Microwave Antennas

设计了2450MHz全裸、半裸、偶极子和挽袖侵入式医用微波辐射天线,通过比吸收率比较它们在体模中的加热效果,研究表明:挽袖天线的加热效果最好,它的加热范围大,形状固定,基本不受插入深度的影响。

The paper introduces four kinds of 2450MHz antennas including noninsulted(bare), insulat-ed-open-tip(I.O.T), dipole-type and sleeve invasive microwave ones.The comparison between the antennas' hyper-thermia performances in the muscle tissue phantom made by specific absorption rate(SAR) shows that the sleeve antenna is the best. It has a bigger heating range and a changeless shape and is independent of the inserting depth.
