In this research project, we have developed a catheter apparatus with an insert dielectric rod and sheet antennas suitable for irradiation of a living body. This is the first application of millimeter-and submillimeter-wave irradiation using an insert dielectric antenna for a biological sample. Tests of time and insertion depth dependent irradiation of a cow liver confirm the normal operation of the irradiation apparatus for living bodies because only the irradiated local part is damaged by the power of microwave well controlledMeasurement results of the denaturation region and the surface temperature of irradiated samples in the irradiation study suggest that the dielectric rod and sheet antennas are appropriate for use as a common catheter irradiation apparatus for living bodies such as liver cancer and brain cancer tissues.Further developments are underway to improve the slim catheter waveguide and to develop an effective antenna to enable localized irradiation.

在本研究项目中，我们开发了一种具有插入电介质棒和片状天线的导管装置，适用于照射活体。这是第一次应用毫米波和亚毫米波辐射使用插入介质天线的生物样品。通过对牛肝的时间和插入深度依赖性辐照试验，证实了该辐照装置对生物体的正常工作，因为微波功率控制良好，仅对辐照局部造成损伤。对辐照研究中辐照样品的变性区和表面温度的测量结果表明，介质棒和介质片天线适合作为常用的导管辐照进一步的发展正在进行中，以改进细长的导管波导，并开发有效的天线，以实现局部照射。
